We discovered these gems while helping a customer clamp a table that had no aprons, which made the glue up extremely difficult to keep square. 3D Squares made an awkward job almost effortless. Now we use them for everything from temporary jigs and fixtures to keeping carcasses aligned during assembly. They are perfect to use in conjunction with pocket hole joinery for interim support until all the screws are in.

3D Squares are made from 5/32" thick aluminum so they won't bend and deform like the plastic versions. You can actually trust them to be square because they are milled to within .002" over their length (we checked them against a Starrett square to be sure). All surfaces are smooth and burr free so they won't scratch. If they do become dinged, a quick stroke of a file or sandpaper is all that's needed. Legs are 6" long outside corner to end and clamp surfaces are 1 1/16" wide. Each square has six 3/16" holes for permanent jig attachment or for temporary fastening when a traditional clamp won't work. Sold in pairs.
