Total price: $0.00
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.
  • Clamp-It® Bar Clamps sold separately

Awesome
The very day I received my clamping square in the mail I put it to work and I have yet to put it down. It is the perfect size and it's got plenty of clamping surface to keep my project square. I love it. Now I just need to buy 3 more.

Put these two pieces together and you eliminate having to ask for help and it helps give you the perfect 90 degree corner.

It will make it easier to clamp boards during assembly, using a speed square is a pain...

I plan to use it for picture frames and small boxes. It should be more accurate then the one I made and will be easier to keep clean from glue

When should I use the Clamp-it Corner Clamping Jig vs. the Clamp-it Bar Clamps?
Jerry on Apr 28, 2017
BEST ANSWER: I work for Rockler. When the material is over 2" wide to be clamped, use the bar clamps. I fit is under the clamping jig works very well.
How many are in a package?
A shopper on Jul 29, 2015
BEST ANSWER: Just one. Clamps must be purchased also. Other clamps will work.
What are its complete mesures, 8"x8"x1.5"x?"...?
