Why do our Fireball squares work better than a speed square?

Clamp directly to the Fireball square’s flange

Cannot clamp directly to a speed square

Fireball squares let you control three planes

Speed squares only let you control two planes

Cast material resists weld spatter

Even DIY welding squares don’t have the same resistance to weld spatter

Fireball square’s tabs and screws allow for better alignment and more configurations

DIY squares lack these tabs and thumbscrews

Most Fireball square designs allow for easy joint access
- 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 300 or 200 mm 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.
- 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.
- 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.
- They are 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.

Pros

| Pros
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. |

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!
