The original Monster Square is available in a 300 mm, 200 mm, 150 mm & 100 mm sizes with two material choices: Cast Iron (FE) with Dragon Scale Coating 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 for mounting tabs.

Patented Design

Use the square to locate tabs precisely

Unlike a ruler, it gives you reference in space and corrects roll so parts line up right.

Set your distance, lock it in with pliers

Now your material runs perfectly parallel and stays put through the whole setup.

Use it to set 90° or 45°

Position your parts fast and clamp them solid for square, accurate weld-ups every time.

Use tabs to prevent twist

Hold parts square and steady through the final weld. Bonus: They grip round tubing too.

Cast Aluminum Mobile Variant

The lightweight aluminum variant is ideal for mobile fieldwork. It acts as a massive heat sink for thin metals and remains completely rust-proof.

Unmatched Manufacturing Quality

Machined flat to tight tolerances, these squares beat standard hardware speed squares.

Clamp it from any side

Multiple faces give you fast, rigid hold without wasting time on tricky setups or uneven surfaces.

Huge Setup Time Savings

Replacing slow manual jigs with this square turns a day of tedious fit-up into a 15-minute task, easily paying for itself in shop labor savings.
