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 series of 3/8" holes 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

To help me build the steamer trunk from the plans I ordered from you a while back. It's going well but as any woodworker you talk to, they never have enough tools. Will probably be back soon. Does your Bissey Clamps ever go on sale? Thanks.

Have some metal ones, but find that even if I clamp tight, they still slip. These look like they will hold better with the fence clamps, but we will see. I use formica samples to protect wood surface so should be OK..

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.
