You might think clamping a 90 degree joint couldn't get any easier with our patented Clamp-It® Assembly Square, but it just did. That's because we're including a pair of Universal Fence Clamps in this all-in-one package! The Clamp-It® Assembly Square replaces custom clamping jigs, acts as a third hand, and eliminates the need for long clamps. Used with the included Universal Fence Clamps, you can assemble any two pieces at 90 degrees, or even a cabinet one corner at a time.


  • Works with any joinery technique, from nails to hand cut dovetails
  • Ideal for every stage of construction, from assembling plywood cabinets to face frames and drawers
  • Clamp-It® is also perfect for framing decks, drawer assembly, and installing rails and balusters
  • Fence Clamps may also be used to secure a huge variety of shop-made auxiliary fences to your existing fences without having the clamp interfere with your work
    Eliminates the need for clunky wood screws and C-clamps or screwing into your expensive fence
  • Use the fence clamps singly as stop blocks, or in pairs for sacrificial fences, half-fences, resaw fences, and a variety of other fixtures
  • Works great for table saws, band saws, cutoff saws, router fences and more
  • Attach the Clamp-It® to a work surface using the Universal Fence Clamps, and it becomes a right angle fixture for bench assembly. Compact, lightweight clamps secure the Clamp-It® Square for tight 90 degree angle joints
  • Clamp-It® features a 3/8'' hole in each leg to accommodate the Universal Fence Clamp Fence Clamps
  • Plus, the Universal Fence Clamps can be used separately with all your shop-made auxiliary fences.
  • Clamp-It® Square's patented computer design is manufactured from high impact, rigid polycarbonate to ensure strength and accuracy
  • Clamp-It® Measures 8" X 8" X 1 - 1/2"
  • Fence Clamps are made of rigid aluminum body with steel threaded components
  • Fence Clamps: Range of travel 1/2"-5-3/4" (1/2" minimum assumes a 3/4" auxiliary fence; you can clamp to an even thinner primary fence if you use a thicker auxiliary fence)
  • Auxiliary fences may need a 3/8" hole drilled to accommodate the Fence Clamps

Woodworking Experience:
Easy to keep pieces square. Used 2 clamps for rip fence extension
I bought them mainly to clamp a rip fence extension to my existing fence. The square plastic does hold project square and firm. All works well.

Woodworking Experience:
The clamps and squares are good quality and an excellent value when on sale. The squares were a bit bigger than I imagined, but that doesn’t cause any issues for my intended use.

Another product I just received, but when I saw it in the magazine I already had other ideas I wanted to try using it for. But in general, I'm very satisfied.

The Clamp-It Square looks useful on its own, and the Universal Fence Clamps look useful on their own. Seems like the obvious solution is to get them as a package deal!

Was looking for a pair of clamps for an aux fence. Found this set with a large Clamp-it square included, it’s a deal I couldn’t pass up! I’ve had 4 mini squares for a while & reach for them more often than I ever thought I would. For the perfectionists out there, they are a must have. Getting the larger size square in addition to the clamps is a bonus in my book— I couldn’t resist & ended up purchasing 2 sets.
TrishA on Apr 18, 2020
Needed fence clamps anyway square is an added bonus

Difference between universal fence clamp it and the corner clamp it jig? Also which would you choose?
Woody on Dec 8, 2018
BEST ANSWER: It depends on what you are using. I use the universal fence clamps for swearing 2x4’s for cornhole frames. Works like a charm. But if I was squaring panels for cabinets I would prefer the jig.
None of the pictures show the "several 3/8 holes" other than the one per leg. Where are the other holes?
Harry K on May 12, 2020
BEST ANSWER: As you have mentioned, there is only one 3/8" hole per leg. The description is incorrect. Thank you for noticing this, I will get it changed.
