There are so many ways to use this square it seems like Magic. It’s two squares in one- when you purchase one Magic Square you get two individual squares that also link together to form 5 different combo squares. A zinc adjustable handle provides tool-less angle adjustments.

Use it as an ordinary, adjustable angle square that adjusts from 40 to 180 degrees.

Right Angle 90 Degree Square with generous weld accessibility. Total height of 200mm in this configuration.

Tall 300mm square when fully opened and locked into place

Remove the fasteners to get two individual squares.

Use the large V-groove to hold large round tubing or pipe.

Switch up mating surfaces to position material in offset positions.

Put the squares back together but with the mating surfaces reversed. This allows you to use the square to hold material offset to each other.

Use a second pivot point on the square with the mating surfaces reversed to change the balance of the square, it’ll seem like an entirely different square tool!

Tips For Variable Angle Settings

One Angle Setting, Two Ways To Hold

  • Each angle you set creates two useful sets of angles on the square. You get the main angle and a complimentary angle (one acute, one obtuse)
  • The most accurate way to get an angle is to use a digital protractor. A scale is not included due to complexities in getting an accurate, high quality scale made
  • Use a 4 inch block with a flat surface as shown below to set a 90 degree angle

Quickly Set 90° Angles

Use Shims or 123 blocks

Use Mega Square

Use Minion Square

Cast Iron


  • Great for heavy duty projects
  • Excellent resistance to deformation and raising burrs when scratched.
  • Some natural resistance to weld spatter.


  • Heavy (Not ideal for mobile welding)
  • Susceptible to rust.



  • Lightweight (Ideal for welding on the go)
  • Resistance to deformation vs aluminum billet
  • Some natural resistance to weld spatter.


  • Can be be damaged if dropped or if used in heavy duty projects.

Customer Reviews

“Great piece of gear! Im very happy with these (I bought 2). They assembled nicely, once you decide to use a wrench for the handles, and seem extremely versatile. The machining is accurate, and quality, these are lifetime tools! Highly recommend to the welder or even woodworker. Yes, they cost more than the garbage at the local big-box hardware store, but they are worlds apart in quality.” – Gene Temple (fireballtool.com)

“This is well thought out- right down to the spring lever handle that can be reset to keep from hitting the square. I also like the smaller size when they are separated. Nice details- either as one or two squares!” – RNeumann (fireballtool.com)

New Dragon Scale

Fireball’s new Dragon Scale coating provides the corrosion resistance of our previous black oxide finish with the added benefit of enhanced spatter resistance. Its 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

6 Edge Location Tabs & Thumb Screws

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?

Tool-less Thumbscrews

But it doesn’t stop there. We reinvented the game by introducing our thumbscrews. Say goodbye to your hex keys 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!
  • 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.
  • The original Monster Square is available in a 300mm or 200mm size with two material choices.
  • The Monster Square is designed to quickly set your work piece to 90 or 45 degrees.
  • Clamping is simple with multiple surfaces for quick and rigid attachment.
  • Use the radius on the tabs to use the Monster Square as a traditional speed square for layout.
  • Compact configuration for use in tight spaces.
  • 150 x 100 x 38 mm, the 100mm width is perfect for picket spacing on gates and fences.
  • Minion Square is the first square we offer which has a built in 60/30 degree angle.
  • The cutout provides just the right amount of joint access when using it to clamp things at 90 degrees.
