Simplify your project assembly process with Woodpeckers new Steel Clamping Squares. What makes Woodpeckers Steel Clamping Squares different from the rest is the reinforcing brace running between the two legs. Our computerized welding system holds the squares perfectly perpendicular while permanently welding the brace. And, these clamping squares are formed from steel, not plastic.

Once they had the fabrication and welding process figured out on the 6" Steel Clamping Square, Woodpeckers realized they could take this design somewhere no other assembly square has gone before…bigger. The 9" Steel Clamping Square is the largest, strongest clamping square on the market. It’s perfect for built-in cabinets and other large casework. 

Bigger is better…some of the time. But, what about your smaller projects? When you’re working on jewelry boxes and other small projects, don’t give up on the idea of using a clamping square to control your results. Woodpeckers make their Steel Clamping Square in a 3" version, too, perfect for those small projects. 

What they didn’t give their Steel Clamping Squares was a hefty price tag. Despite all-steel construction, the unique reinforcing brace, and a tough powder-coat finish, These squares are very competitively priced, and they’re compatible with most “F” “C” and spring clamps. Better than all of that, these new Steel Clamping Squares are held to a tolerance of +/- .0255 degrees!

Woodpeckers Steel Clamping Squares are available in 3", 6" and 9" sizes and come in sets of four with a wall-mountable Rack-It™. We also offer a Master Set with four each of all three sizes and three Rack-Its™.
