Workshop Square Helios Preisser model 0372107 — cross-section 32×7 mm, leg lengths 300×175 mm

Helios Preisser Workshop Square model 0372107 is a metal engineer's square with a cross-section of 32×7 mm and leg lengths of 300 mm and 175 mm. Designed to provide a rigid and accurate 90° reference, this workshop square is suitable for layout, marking and inspection tasks in metalworking and carpentry. The solid construction and straight edges allow reliable transfer of right angles and verification of squareness on workpieces, fixtures and machine set-ups.

Advantages

The workshop square features a robust metal profile with a 32×7 mm cross-section that resists bending and twisting during measurement and marking. Its precisely machined faces and sharp corners ensure consistent 90° references for checking squareness and guiding cuts. The differing leg lengths (300 mm and 175 mm) offer flexibility for both larger and smaller workpieces, while the compact design is convenient for storage and transport in a toolbox or on the bench.

Suitable for

• Checking and transferring right angles in metalworking
• Squareness inspection of machined parts and assemblies
• Marking and laying out lines for cuts in carpentry and joinery
• Setting up fixtures, jigs and machine references
• General workshop measurement and quality control tasks

Key specifications

• Cross-section: 32 × 7 mm
• Leg lengths: 300 mm and 175 mm
• Material: metal construction suitable for workshop use
• Reference angle: 90° machined faces
• Finish: machined edges for accurate marking and contact

How to use

Place the longer or the shorter leg of the square against the workpiece edge depending on the required reach, ensuring full contact along the reference face. Use the opposite face to mark or scribe the perpendicular line with a pencil, scriber or marking knife. For inspection, press the square firmly against the edge to reveal gaps or misalignment and adjust the workpiece or fixture until the faces sit flush. When guiding a saw or router, clamp the square securely or use it in combination with a sacrificial fence to maintain a true guide without damaging the precision faces.

Usage recommendations

Store the workshop square in a dry place and keep the machined faces free from burrs, paint or heavy corrosion. Clean with a soft cloth after use and avoid dropping or striking the square to preserve accuracy. For critical inspection tasks, verify the 90° angle periodically against a calibrated reference.
