The original Monster Square is available in a 300mm or 200mm size with two material choices: Cast Iron (FE) or Cast Aluminum (AL). All Monster 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.

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!

4 Edge Location Tabs

Our revolutionary tabs allow you to align your material up so that you don’t even need a welding table! Don’t spend thousands on a flat table, just use our squares! Tighten the tabs onto the front or back of your square and you can immediately get to work. Sure, there are different jigs out there, but can they line your material perfectly in seconds?

4 Tool-less Thumbscrews

But it doesn’t stop there. We reinvented the game by introducing our thumbscrews. Say goodbye to your hex keys and Allen screwdrivers and freely adjust the tabs with only your fingers!
