Frequently bought together:


Like perfect minions, these squares are compact, come in sets, and are ready to hold your work when summoned.

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.

Bosses on the square allow mounting of tabs to both sides of the tool.  

Squares are sold as a "left and right" pair, each pair will come with 2 squares, 8 tabs, 8 thumbscrews.

Compact Size For Tight Spaces

4" Width Perfect For Picket Spacing

Clamp The Angles Together To Create Custom Spacing

Cast Iron vs Aluminum

Cast Iron


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


  • Heavier



  • 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.

Included Accessories

4 Edge Location Tabs

Each square comes with 4 of our new compact tabs measuring 1-3/4" (1.75) long x 5/8" (0.625) wide, and 4 of our newly designed thumbscrews to provide tool-less adjustment of tabs.

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!

What is Black Oxide?

Black Oxide, blackening, oxidizing, oxiding, black passivating, gun bluing . . . these terms all refer to the process of forming a black iron oxide on the surface of ferrous metals.

The black oxide process is a chemical conversion coating. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating. Instead, the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution. These oxidizing salts include penetrates, catalysts, activators and proprietary additives which all take part in the chemical reaction. The result of this chemical reaction is the formation of black iron oxide, magnetite (Fe3O4), on the surface of the metal being coated. Black oxide has a range of unique properties and benefits including corrosion protection & reduced friction.

Our Other Squares

  • 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 12 or 8 inch 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 8” in this configuration.
  • Tall 12” 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

    I made a point of getting back on line to leave this review. I’m a crappy hobbyist builder, make carts, racks, stands and everything else. I bought these pricey jigs hoping to speed my work up. Well doggies not only did it speed up I haven’t had to square a box since .. once you clamp it up, it’s square corner to corner . I’ll be buying more for sure.

    Useful Tool

    Posted by Chris on Sep 23rd 2021

    These squares are really nice, really well made, and very useful. I give them 4 stars because without a beveled corner you can't use the long side(s) to check for square after something is welded.

    10/10 on theses little guys. Super precise and heavy duty. As a small one man shop I’ve already put these to many uses and love them.

    Excellent Quality

    These were a second buy for me from Fireball; they are top quality and are incredibly useful for squaring up pieces before welding them together. Well worth the money!

    Minion squares

    Posted by Greg on May 5th 2021

    Bought a pair and should have bought two. Would have given 5 stars but the black oxide finish was quite messy. My hands were black just taking them out of the package. Smaller size works well is tight spaces.
