Aluminum (AL) Cast Iron (FE) Dragon Scale (FE)

Pros

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

Cons

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

Pros

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

Cons

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

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.

The original Mega Square is available in a 12", 8", 6", 4" size with two material choices: Dragon Coated 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.

All 12" & 8" Squares Made in USA - Patent Pending

Roomy joint access for welding, gluing, nailing, riveting, etc.

Tabs help eliminate twisting and warping in the final work-piece.

 

Clamping is simple with multiple surfaces for quick and rigid attachment.

The original Monster Square is available in a 12", 8", 6", 4" 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.

All 12" & 8" Squares Made in USA - Patent Pending

Designed to quickly set your work-piece to 90 or 45 degrees

Tabs help eliminate twisting and warping in the final work-piece

Use the radius on the tabs to use the Monster Square as a traditional speed square for layout.

COMBINATION SQUARE

The Fireball Combination Square Blade comes in a unique finish and graduation marking scheme. Our finish is a titanium nitride coating which gives it a gold color that provides great reading contrast. This is the same gold finish used on drill bits which is both extremely durable and scratch resistant.

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

These squares come in a compact configuration for use in tight spaces. Each square measures 6" x 4" x 1.5", the 4" 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 also provides just the right amount of joint access when using it to clamp things at 90 degrees.

Compact Size For Tight Spaces

4" Width Perfect For Picket Spacing

Clamp The Angles Together To Create Custom Spacing

3-AXIS SQUARE

  • Use the inside or outside faces. 4 machined faces on both the inside and outside of the square.
  • No limit on inside face, large 4” height limit on outside face,
  • Ductile cast iron for tensile strength
  • Balanced to sit on its front feet, with additional small magnets on the front feet to resist tipping.
  • Feet of the square are 1” wide to match our Fireball Fence Block fixture system
  • Tapped holes in both feet for installing pins that quickly align the feet with the 2” grid pattern of common welding tables

MUTANT SQUARE

The Mutant Square is 10x10x2 inches in size.

Its size slots in between the Monster 8 square (8x8x1.5") and the Monster 12 square (12x12x3").

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!

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!
