The original Mega Square is available in a 12", 8", 6" & 4" sizes with two material choices: Cast Iron (FE) with Dragon Scale Coat 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 for mounting tabs.

All 12" & 8" Squares MADE IN USA. - Patented Design
Roomy joint access for welding, gluing, nailing, riveting, etc.
Whatever process you’re working with, it probably benefits from some clearance around the joint.
Tabs help eliminate twisting and warping in the final work-piece.
The machined squares and tabs always create the perfect plane for your work-pieces to rest on. Tabs also let you easily hold round tubing.
Clamping is simple with multiple surfaces for quick and rigid attachment.
Stop spending your time and focus figuring out clamping strategies, or worse, clamping your straight workpiece to crooked surfaces.

Cons
| Fireball’s new Dragon Scale coating provides the corrosion resistance of our previous black oxide finish with the added benefit of enhanced spatter resistance. It’s spatter resistance needs to be seen to believed; it out performs even the best weld spatter sprays without the use of any sprays. |
Included Accessories
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!
Optional Add-ons
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!
