Mega Square
The original Mega Square is available in a 300 or 200 mm size with two material choices: Cast Iron (FE) or Cast Aluminum (AL). All Mega Squares feature a stiff “flange and web” design that is fully machined on all outer edges with tapped holes on the sides for mounting tabs.
- The Mega Square is designed to quickly set your workpiece to 90 or 45 degrees.
- Tabs help eliminate twisting and warping in the final workpiece.
- Clamping is simple with multiple surfaces for quick and rigid attachment.
- Roomy joint access for welding, gluing, nailing, riveting, etc.

Edge Alignment Pins
Install our edge alignment pins on any square to create a large, overhanging edge which can be used to index the square on a different plane. Depending on the square, this allows you to create edges which are 90 degrees (perpendicular), 45 degrees, parallel, and even 60 and 30 degrees from the edge.
- Use it with our Monster squares to create a speed square for layout.
- Use it to hang the square off the edge of a table for working vertical or perpendicular to table surface
- Use it to elevate the squares off the ground or table for extra clearance when you’re fitting and welding entire frames
- Tip! If trying to create a parallel edge with the mega square for marking, use our shims to get that perfect distance!
