Overview

Here's a solution that's so simple, you'll wonder why it took so long to develop! The Clamp-It® replaces custom clamping jigs, acts as a third hand, and eliminates the need for long bulky clamps. Simply put, the Clamp-It® is a square you can clamp. In fact, you can even assemble a cabinet one corner at a time! Works with any joinery technique, from nails to hand cut dovetails.

It's ideal for every stage of construction, from assembling plywood cabinets to face frames and drawers. Clamp-It® is also perfect for framing decks and installing rails and balusters. Attach it to a work surface, and it becomes a right angle fixture for bench assembly. Clamp-It® is computer designed and manufactured from high impact, rigid polycarbonate to ensure strength and accuracy. Size of the Clamp-It® is 8" X 8" X 1 - 1/2".

Great for:

  • Drawer Assembly: Clamp-It® is designed for use on either the inside or outside of a corner, making it ideal for assembling drawers with lipped fronts.
  • Deck Rails: Use Clamp-It® to hold deck balusters at a perfect 90° angle while fastening.
  • Bench Jigs: Clamp-It® can be secured to any work surface to create a simple 90° assembly jig.

I used one of these squares on a small cabinet I just made, it was great, so I ordered another as assembly would be faster with two.

Thought I would give Clamp-It Assembly...
Thought I would give Clamp-It Assembly Squares a try so I purchased two to use in my shop. I have a very large project to build and clamped the Clamp-it squares to upright 2x4s to act as a third hand. They worked so well that I have just ordered six more. They held everything squair and secure while I worked. I wish I had a set of these a long time ago they would have saved me a lot of time. Could not live without them now.

Having the clamp it is like having a helper in the shop with you, and you can do so much with so little its just a great tool

Clamp-It Assembly - great for me!
I bought a pair of these and a pair of the adjustable ones about 2006. Since then, I built 50 or so large frames for an artist who needed canvas stretcher frames from 5' x 5' to 12' x 7' (various sizes, by requirement). These squares were wonderful and the artist sold her paintings for $5 to $20 thousand. She told me she got compliments on the quality of the stretcher frames from quite a few customers. She moved away so I just use these for whatever I need them - they still work great!

I bought 4 of these clamps thinking that I could use them in my business. Turns out not a one of them is actually square. They are about 1/32" out of square in the length of the leg. They are worthless for use in a professional setting.

The assembly square is not dead on square and the surfaces are not flat. Not a precision tool. Good for rough assembly.

I was quite disappointed in the Clamp-It Assembly Square. It is at least 1/32 out of square over the short 6" length. This expands to a much larger error over a 28" length of my cabinet. I will try to square up the Clamp-It but don't feel I should have needed to.

I cannot share the enthusiasm for the product with other contributors. I found that, yes, once you have the pieces clamped in place it is like having a third hand at least and an assistant at best. However, I find it very difficult to allign the pieces and apply the clamps in the first place. Maybe because I have two left hands but so far I have found the product more frustrating than helpful.

Great idea, but unless three of my squares are wrong, each wrong in the same way, then these aren't square. Which would seem to me to be important.

Poor execution,
As several others have pointed out, these are molded and have ridges that interfere, in addition to not being square, possibly due to shrinkage while cooling. The internal bosses on the squares also make the clamping surfaces wavy. Those of you who gave these five stars, I wish you well with your projects. These are not professional grade.
