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!

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!

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.
