All-In-One Low-Profile Contractor Clamps

Item #
84% of 100
Lower profile and wider jaw creates more stability! Wide lever handles and a click-lock sliding jaw make it simple to position and secure these clamps for use as a straight edge guide for circular saws and routers and as a fence for your table saw or drill press. A very low 17/32" profile body and flat top allow many applications without obstructing tools. Easy-to-read full color measuring scales enable outstanding accuracy anywhere along the clamp. Onboard T-Tracks fit select clamp accessories, sold separately. Rigid, lightweight construction makes these clamps a joy to operate. Each clamp is 2-1/2" wide. Contractor Saw Plate (#33408, sold separately) and Contractor Router Plate (#38428, sold separately), Stop Block (#31481, sold separately) and Squaring Attachment sold separately.

Woodworking Experience:
Excellent addition to my shop
Having the 8-foot and 4-foot versions of this clamp, I had been looking to add this 2-foot version to help deal with shorter, cross-board cuts (especially since the 4-foot version, was a little inconvenient to use in some situations). It works like a charm and is a good addition to the suite of tools I use with my circular saw (and router), especially when dealing with long, narrow stock that won't go through the table saw for cross cuts.

All-in-One clamps
Clamp is easy to use and set up. I initially purchased the 50 inch clamp to use as an edge guide for circular saw to cut large plywood panels. This worked well for me, so I now purchased the 24 inch clamp to use with smaller panels. The built-in scale on the clamp is a nice feature.

Great Purchase
Overall it does exactly what i want, straight rip cuts. Some commentors complain of it bowing, i had it happen as well then i realized i secured it in place entirely too tight. I have yet to use a router but i do plan on it soon.

Wish I had gotten sooner!
Been struggling to make over-sized rips on my contractor table saw with limited success. Finally got one of these guys, and wish I had gotten it sooner!

Throw the piece on some saw-horses, mark your cut line, then mark your circular saw show offset, and clamp down at the offset line.

They are not self-centering by themselves - so you will need to mark at least your off-set line across the work-piece, so you can clamp this guy right on that line for a clean cut.

I suspect the 99" version is made of two pieces with a connector. Is the connector well made so that the pieces maintain a continuous 180º precise cutting edge which doesn't flex?

BEST ANSWER: All one piece

Bora WTX Circular Saw Plate for Clamp Edge Saw Guide
Description of straight edge clamp states "new and improved". When was item improved?
David H on Nov 6, 2016
BEST ANSWER: Not sure exactly when it was changed but I have one from about 8-10 years ago that did not have a scale on it and was narrower
can you skew the cut on 4x8 sheets so that I can cut 16" down to 15" - 48" wide?
Philip on Apr 24, 2015
BEST ANSWER: The clamp is long enough so you can skew it 8-10”, but the clamping mechanism is designed to work at a 90 degree angle. It might hold on a 1” skew, but you might bend the clamping mechanism or the entire length of the clamp might bend/warp. You could either use shims so the clamping mechanism has a flat surface to clamp too, or use C clamps to hold it in place.
Can this clamp be used as a table saw fence?
Brad U on Mar 26, 2017
BEST ANSWER: Maybe, the edge of my cast iron top has a chamfered edge and I think that it cuts deep enough to keep the feet from grabbing the top. If you're table saw top has a square edge from the top to the side, I wouldn't see why you couldn't use it as fence.
Do you have any information about how to use this clamp? Specifically the jaws, I'm having trouble locking the rear jaw...
Stan T on Jul 12, 2017
BEST ANSWER: Here is a link that can help you with that.
Do they make fixed router,circular saw, and stops guides for these?
David B on Mar 18, 2018
BEST ANSWER: They make a couple router guides for this clamp. I have one of them & it works great. I don't believe they make a saw guide for this clamp. As far as the stops go not to sure,
I just simply made my own stops with blocks of wood and some clamps. Ingenuity can go a long way. Have you searched Rockler lately for these items?
My saw guide is not holding tight when clamped. What am I doing wrong?
William B on Jul 7, 2017
BEST ANSWER: I can visualize two possibilities. One is that you are clamping thinner stock and it is causing the stock to buckle which would make the clamp come loose. the other is in putting the clamp on the board. The clamp handle needs to be in its released position (up) and then slide the grip at the other end of the clamp up to the board tightly. Then push the clamp handle down to secure the clamp.
The instructions state that the 2 pieces have to be pushed till a click is heard for secure lock. Please explain how to lock it to the correct length. Do I just move the movable side next to the board without trying to hear that click and lower the fixed lever to tighten? Is that enough? Thanks
Maged B on Nov 26, 2016
BEST ANSWER: It's a great question. Yes, first make sure the blue handle is either flat or facing up, then move the movable side of the guide and press it to the work piece. You should hear a single click. Then make sure your guide is still exactly where you want it then apply a little downward pressure to the guide to hold it in place while you lock it in place by pushing the blue handle down in the locked position.
Regarding the 24" & 36" clamps; are these a set fixed length [24" or 36"] minimum or can each be used on widths smaller than their specific size, e.g., can the 24" be used on 12" to 24" widths or the 36" be used on "24" to 36" widths?
david on Sep 22, 2016
BEST ANSWER: These clamps can be used on any width shorter than the length of the clamp.
Can 2 clamps be connected end to end to make longer?
David R on Sep 13, 2016
BEST ANSWER: These guides are not designed to add to each other.
I'll be cutting 8 ft. sheets, but for monetary economy, i would like to use it for small pieces like the 48 inch side, etc.,-- is this overkill or should i purchase another clamp for smaller cuts since this large 99 inch might be cumbersome?
gene k on Jan 12, 2016
BEST ANSWER: The clamps grip very strongly when adjusted properly, so your plan will provide a versatile, cost-effective solution, so long as you have a large enough workspace to maneuver them (which I imagine you likely do if you're cutting 8ft board). I've used a 39.5 inch clamp to make cuts as small as 6 inches without any issues. Just be sure to place the clamp on the side of the board that will not fall after the cut is made (or support it independently) in order to eliminate the larger clamps desire to twist the board as your cut progresses. Also, if the board is thin then extra support may be needed for the above reason, before the cut even begins. The clamps are by no means heavy or cumbersome but when they are twice the length of your cut or more, such measures may be necessary for precision and safety.
