PATENT PENDING

Meet the Donkey Carpenter Square — built for fabricators and welders who demand square, accurate setups without the bulk of large fixtures. Designed to function like the jigs you already trust, but styled like the tool you recognize, this square gives you clean alignment, faster fit-up, and the flexibility to work on pipe, plate, or structural assemblies.

Features

  • Solid Construction — Machined from high-grade aluminum for durability with minimal weight.

  • Square-Style Design — Traditional square geometry offers intuitive positioning and reference surfaces in one tool.

  • Versatile Setup — Use it for pipe to plate, plate to plate, trunnion fit-up or structural splices — the square shape adapts.

  • Precision Alignment — Flat reference surfaces and rigid mounting points keep joints square and reduce re-work.

  • Made in the USA — Crafted with the quality and attention to detail you expect from Dale Hermann.

Why Fabricators Choose the Donkey Square

  • Simplifies alignment tasks by combining the reference surface of a carpenter’s square with the fixture-power of a jig.

  • Reduces setup time while ensuring true 90-degree orientation in fit-up situations.

  • Ideal for field or shop use where a full jig may be too large or bulky.

  • Offers a compact solution without sacrificing precision.
