Component Descriptions

  OTLVISE Clamp frame 2.5 inch capacity- There is a special laser cut wrench that should be the only tool used to tighten the Main clamp pad screw.  NEVER TIGHTEN THE NUT DIRECTLY BEHIND THE DISC, this is a fixed position and that's why there is a set screw there.     ALWAYS make sure that Disc is evenly spaced and NOT tilted when tightened. A Spacer block is provided for this issue.  For example, DO NOT TRY TO clamp down a broom stick outside the center of the disc.  Anything to be clamped must have even pressure on both sides! A spacer block 3/4 inchand roughly 11\16ths has been provided as these are the most common sizes required. Other dimensions can easily be improvised by stacking formica sample chips and taping them together. Clamping to painted surfaces will require user to gently pry disc from object as it will be stuck on from the paint. Remember to use the safety hole on disc when needed by either anchoring with a screw or by adding a bolt as shown in the VIDEO section to secure the slate.  The Clamp also provides a kickstand which also serves as a Safety Support.  Review videos! Working load per clamp is 300LBS. 

DO NOT TIGHTEN ON GLUED AREAS WITHOUT using countermeasures as shown,The Baby Powder will do it or a dollar bill.

A drop of oil behind the disc between the washer and STOP NUT will reduce wear and make for longer use before replacement would be needed.

When replacing E-clip  on clamp head exercise caution and WEAR eye PROTECTION IN CASE IT flies up into your eye. NOT likely but possible.

DO NOT USE Padding on clamp head disc when moving slate....

OTL-Wrench-use this wrench provided only when tightening OTLVISE..  Never use add/ons or large wrenches or pipes.  You will damage the OTLVISE and have to buy another.  This can be attached to a quick pin so you don't loose it or hang it on the fulcrum hook and always have it handy.... Use the other end to check the tightness of the bolts on your unit!  The SAFETY Wrench for anchoring slate which is RED also can be used so that means You get 3 wrenches within a KIT.

Cart Handle\Double wide- 2 handed, in close handle for moving in tight areas etc  NOT to be used with Handtruck Attachment as it would be too close to be useful.  Perimeter holes allow you to create a unified handtruck with bottom axle and 2 more clip attachments. This can also be used as an axle for moving Shuffleboards.  Or can also be used in conjunction with axle to roll slate on 4 wheels.  

Handtruck handle attach-12 inches wide, #8 + #10 handles mount to it

Handtruck Lower Lip-
you can make yourself a cool Work Center Cart (WCC).  Its easier and faster to use a cart.  Customize your own.  It will save you over 10 mins a day on average which over the course of a year is an entire week.  Next time you carry your tools, forget something and keep going back to the truck, wish you had better lighting and more, just remember OTLVISE.  Best part is you can detach the wheel assembly and use it for another function.

Single cart Handle-
allows front man going up stairs to walk forward and not backwards.  This handle has a hole in the extension for "add on" handles under research.  DO NOT USE the hole feature until the best add on handles are developed.  THE hole can receive a longer piece of pipe for heavy lifting.  Example would be one piece slate.  You can also create Your own handles to slip over and lock in if desired.

Slate Shoe- protects product being moved,has predrilled holes so you can attach items being transported with screws for extra safety when appropriate. This must be seated flush at a right angle with the media being transported.

T-Handle-  great for lifting or pulling,  recommended for Handtruck.  As with other OTLVISE handles there are various positions that you can locate the handle to in respect to centering on load.  Always try to keep load centered. Its reversible to make going up or down stairs easier.  

Handle screw- Quick no tools required handles for tightening, used best when carrying multiple items.

V Saddle-  move sheeted material when used in conjunction with the axle assembly.  This and the Universal Lower mount can also be used independently with the new axle attachment. The MAST can be made from a simple piece of Pipe but as stated the Pipe is NOT included due to shipping costs.  This Frame Dolly attachment is also useful when moving one piece slate as shown on video.

Wheel mount- Axle assembly 5/8   Remember that the load is limited by what wheel you use.  Check the capacity of the wheel before you use it to make sure it will be strong enough. There are 3 sets of holes for registering loads to keep them as balanced as possible.  Just slide to either side and anchor with bolts,lock washers.
This unit should be bolted on, PERIOD.  Lightly grease axle for regular maintenance...

4 FOOT Slate Shoe- 1\4 inch steel desgined for large pieces of Marble, slate etc. Future lengths will be increased so you can have various size carts.

Benchtop OTLVISE Universal anchor- Use this to mount your Otlvise and you can quickly remove it for portable use.   Great way to hold things with the other shoes as well. Simple piece of channel has many uses.  Also great for holding rails sideways when putting on new rubber for example.  Make a skinny axle and more..... 

 Fulcrum  Clip- Use this in conjunction with other slidable components to assist in moving media.  Can serve as extended handles,upright support pole and more.  The Power of the Fulcrum...  Make sure pole always goes up to the

12 o'clock position on each stair....  watch vids its easy    Check for clearance.... 

Do’s and Don’ts


Review entire Website!!!!

USE safety features:

“Clamp Head” has holes for screws\bolts to anchor material such as slate within the rail bolt holes, wood backing or just drill out a hole if there isn't one

Use the Kickstand as a safety anchor for your "slate hanger" and or "slate Cradle"

Use ratchet straps on BILLIARD SLATES to add safety factor

You can also drill out the back of the “slate shoe” for anchoring antique slate or Billiard Slate

            “Slate shoe” has holes to use with bolts\screws

            It only takes a minute or two to use these CRITICAL  SAFETY features

Make sure you have a clear pathway

Remove throw rugs or items that may cause your feet from slipping or tripping

EVEN Pressure is required on both sides of clamp

Use scrap piece of wood\stock to fill voids so clamp has even pressure on both sides if needed

Read Instructions - Watch videos

Only use wrench provided, larger wrenches will apply TOO MUCH Torque will damage Clamp

Use Grips on handles to maximize your strength, pick out your own that fits best from the Bike Shop

Check tires for even pressure and that rims aren’t bent

Check size of stair treads to make sure tire can land and rest on each step if needed

Use “Wheel Chocks” as mini ramps where possible to make moving easy

Make sure people\pets are clear of area while you move items

Check your cotter pins\quick pins on axle

Make sure you have “spacer washers” on axle for a snug fit to prevent wheel travel

Use Common sense

Have helper if weight is too much for you

Purchase additional axles etc to move extremely heavy slate or other heavy articles

Email questions before guessing about something

Be careful when using on sides of hills, have helper stabilize load if top heavy, traverse the hill if too steep by going sideways up or down slowly...



NEVER go backwards down stairs

Don’t try to take “Short Cuts”

Don’t load beyond the rating load of wheels that are used

Don’t use in wet or icy conditions that will cause you to slip

Don’t use inferior tires and rims, purchase GOOD wheels

Don’t allow anyone else to use without showing them Safety procedures


Never Run with unit in use

DO NOT drop on wood floors or ceramic tile it will damage them

Use on white carpet if you have black tires and wet, might leave marks

Don’t drop on toes etc it will hurt and cause you injury

Don’t leave units in extreme heat as this will loosen adhesives and cause slippage

Don’t try to move more weight than you can easily handle on your own

Don’t use earphones\headphones while moving

Don’t over tighten

Practice with 7 or 8 foot slate first, don't try moving larger pieces until you have familiarized yours

DON'T USE the Front Wheel on Kickstand when using Fulcrum Hook

Don't use ramps going down stairs, using on the one last step going up the stairs is best --- Also helpful turning sideways for sliding doors or large first step.. 

Using Attachments


When Wheels are placed on axle attachment there may be the need of washers since all wheels are not the same size.  Having the wheels ride straight and true is best achieved when there is little play on the outside axles.  You need to purchase these when you buy your wheels to match your hubs if you need more.  8 washers are provided in KIT. 

The axle is 5\8 and can hold many wheels with a width of 3 inches per wheel on either side of the axle.  The tires need to be at that same pressure or you risk tilting the load and reducing the ease of control.  Remember to add Tennis balls to protect the outside of the axle from damaging anything just in case.  The Wheels will be a Customer Preference as there are too many options and many people prefer a certain style. MARATHON 14 Inch Air tires have proven to be the best tire...

When rolling heavy items make sure they are NOT top heavy and avoid using when the grade of the ground is too steep.  Sometimes better to put wheels in the middle and turn slate for example sideways.  This lowers the center of gravity and will make it easier.

When loading slate on an inclined driveway for example: you need to have the direction of the slate going the same way as the driveway so when you load the slate it is parallel to the ground.   SLATE MUST NOT BE PLACED IN VISE ON UNEVEN Ground.  This will cause the Disc on the OTLVISE to be off angle and damage it.  DON'T APPLY PRESSURE UNITL YOU HAVE SQUARED THE SLATE IN THE UNIT!


Some stair treads may be too small for the wheels you have chosen.  Be sure to check stair treads with wheel size BEFORE using unit.  Example:  Stair tread going down Bilco door stairs is short and large wheels will have no where to land.  Some stair treads are cracked on the lip where you will be rolling product.   Always review condition of stairs before using.  Air filled tires will provide a softer landing versus "NO FLAT" solid filled tires.  Tires should always land on the inside of stair tread on NOT on the overhang lip leading to the next - avoid bouncing out of control down the stairs! Take your time and be CAREFUL!
FAILURE TO USE SAFETY PROCEDURES may cause SERIOUS OR FATAL INJURY to You or People who shouldn't be in the area when YOU are moving slate.  In Particular on stairs! 

Before use, YOU MUST inspect your travel path and clear it of any obstacles!  While IN USE, YOU MUST NEVER ATTEMPT TO PULL OR PUSH THE ITEM YOU ARE MOVING IF YOU DO NOT HAVE PROPER FOOTING!!!!!!!!!!!!!

For example pulling up with\while your feet are on a loose carpet, or you are on mossy stairs, mud, snow, ice water….  Any time there is a potential for slipping you MUST EXERCISE EXTREME CAUTION!

 If the stair tread length is shorter than the footprint of the wheel, the wheel will want to automatically roll down the next step which is DANGEROUS.  YOU need to check the stairs when you’re going through your dry run for this potential problem.  Having another size tire which is smaller with you is recommended.  Two sizes will do almost any stair pattern. NEVER USE WHEELS OR TIRES THAT ARE NOT THE SAME MAKE MODEL or use one size on one side and a different size on the other.

The unit should NEVER be used pulling a load backwards unless the wheels will stay in constant contact with the ground.  For example:  your pulling slate up from stairs with BILCO doors out of a basement.  Once you get to the top, you’re stuck.  In this case, small ramps will allow you to continue to roll the slate for example.  Just as you would not use a handtruck backwards going down stairs.  BE SAFE! 

Remember ramps make the job easy and safe.  Some are small for the first and last stair. Some for traversing 2-3 steps at a  time. USE RAMPS RATED FOR THE WEIGHT YOUR MOVING
When loads are being transported: the top handle should take weight and pressure off of the axle by tilting the load backwards into a lower position before going down the first stair. . This method of shifting the weight back into the handle is important when you go down the first couple of steps.  Keeping the weight back allows the axle and wheels to move down the step easier and with more control.   The load must be kept in a secure position to avoid the hazards of the operator letting it loose.  Heavy loads require a spotter to make the task as easy as possible.
When two people are working together the FULCRUM Attachment can be used to go up or down the Stairs easily.
NEVER attempt to move a load you can't safely handle on your own!

Adding additional wheels for long distance moving is easy, turn it into a wagon and just push it.  

When using the Slate Shoe it must be back all the way into the vise sitting as flush as possible. 

All of the attachments operate with the basic instructions above.  IF the attachment is bolted on, there is little chance of it coming off.  QUICK pins work fine but again, YOU MUST USE THEM IN THE UPRIGHT POSITION!!!!!!!  DO NOT USE THEM ON THE AXLE ASSEMBLY as an added safety precaution.

Handles are designed to be offset so that when you go up stairs they lay flatter in your hands making it easier.  The Single pull handle has hole for future handles to be added on with quick pin\bolt.  DO NOT ADD anything on this HANDLE  or you VOID WARRANTY-IT IS FOR FUTURE ATTACHMENTS for you to enjoy and use.

 Make sure you have clamp supported on both sides so the disc is balanced. Never operate clamp with uneven pressure.  The clamp is designed for FLAT things, DO NOT for example try to tighten a broom stick handle.  If you don't have it exactly centered you will Damage the unit!  USE A SPACER BOARD to fill in gap behind clamp head or the Slate Shoe if necessary.  You can carry this by keeping it on the fulcrum hook.
Practice with a lighter load until you become familiar with the handling characteristics.  Try 7 FT slate up and down stairs as practice first.




Check your padding on the Slate Shoe to make sure it hasn't loosened, remember to keep out of the sun so the heat doesn't loosen adhesive.

Check STOP Nut in back of disc and make sure it is still tight, DO NOT TIGHTEN THE NUT DIRECTLY BEHIND THE DISC!  Check set screw in STOP NUT and also make sure this is tight.  Too much torque may cause this to loosen.....( AVOID unneeded wear by making sure the slate is vertical and square when loading, DO NOT LOAD SLATE sideways on inclines!  Turn UNIT towards the Hill to load evenly....) Refer to video on CLAMP Assembly or CALL ME.  With continued use the STOP NUT will wear and the washer between it and the CLAMP HEAD will need to be replaced with a thicker one to reduce chances of the head coming loose and causing problems. Again See assembly video....  Be sure to clean the threads of the clamps as they build up with dirt and lightly grease. Add a drop or two of oil between disc\washer and Stop Nut to prevent excessive wear.  Failure to clean will cause excessive wear.   A Maintenance KIT with thicker replacement washer and others items is provided. At some point the main screw will likely need to be replaced...  Extend the life of your tool by using it properly.... Many users have had it for years with NO WEAR Problems. If you have worn the nut down to the "SET SCREW" its time for a new "DRIVE SCREW"...

Clean and grease the main clamp screw so it turns freely, not too much grease or it might drop onto a customers carpet etc!  A visual inspection is important and you should always inspect before use. 

Check quick pins and bolts for tightness..... when using bolts make sure you use lock washers on them with the clamp attachment on axle. Regular use may cause bolts to loosen and its important to check these.  The wrench provided is configured to do this.

Check tires for even pressure, keep a spare if you want - its easy to pop on.  Be sure to replace wheels when worn and don't use bald tires.

Check wheel cotter pins or quick clips to make sure they are functioning properly.  Keep wheels as tight as possible on axle with washers.....


When switching out for the Handle\Knob assembly unit you must tap and thread both pieces and wipe clean before unscrewing them completely.  Debris from the set screw could bind up the threads if not removed with tap set. Then your OTLVISE will be damaged by you if you take a shortcut and don't clean up the threads where the set screw was holding the lock nut.  Review video and note that disc is firmly snug against the lock nut when finally set and tightened back together.   

When using as MWC(Mobile Work Center) make sure heavy loads are placed on bottom of cart. Make sure loads are secured.

When using as Mobile Advertising: watch out for power lines, DO NOT leave unattended, never ride on unit,never run with unit, use common sense

NEVER have anyone other then you and your spotter in the path of where the slate or heavy items are being moved.  Example: you’re moving something down stairs and someone else is at the bottom or possibly coming around the corner and you let go of the item being moved.  The weight of the item coming down the stairs may cause serious damage if you let it go prematurely.  Clearing people or things out of your way\travel path is very important in safely moving loads. AVOID OBSTACLES

Units are made of steel, when dropped on foot they will cause injury. DO NOT drop!

Dropping Lolli-Pop Handle will potentially cause it to break, take of your tools.

DO NOT make pulling handle too long or it will get in your way when your going up stairs.  33 inches works for most people.

DO NOT use a carpet\blanket under boards to land slate as it will slip, bare boards with non-slip material work fine.
Do NOT use with loose tied shoes\sneakers or open toe sandles. 

Wear proper close fitting clothes:  Do NOT wear baggy pants while moving slate
