Metal Carpenter's Square Helios Preisser 50 x 28 cm model 0375418

Helios Preisser metal carpenter's square model 0375418 with dimensions 50 x 28 cm is a precision right-angle tool for marking, measuring and checking 90° relationships on metal and wood workpieces. The square features rigid straight edges and a robust construction intended for repeated use in workshops, on construction sites and in fabrication tasks where accurate layout and verification of right angles are required.

Advantages

The metal construction provides stability and good wear resistance for frequent use. Long, straight edges support accurate scribing and visual alignment across workpiece surfaces. The 50 x 28 cm size balances reach with control, enabling layout on medium and larger components while remaining manageable for hand use. The simple geometry and flat profile make the tool suitable for use with pencils, scribers and marking knives, as well as for checking squareness after assembly.

Suitable for

• Carpentry layout and joinery marking
• Machinist bench checks and metal fabrication
• Checking and setting right angles on assembled parts
• Workshop measuring and verification tasks

Key specifications

• Material: metal construction for rigidity and durability
• Working size: 50 x 28 cm measuring faces for layout and inspection
• Flat straight edges suitable for scribing and visual alignment
• Profile: thin, rigid blade and stock for tight contact against workpieces

How to use

Place the stock of the square firmly against one reference edge of the workpiece and align the blade along the surface to be marked or checked. Use a pencil, scribe or marking knife along the blade edge to transfer a 90° line. For verification, press the stock squarely to the reference face and inspect the contact along both edges to confirm there are no gaps. When checking assembled parts, ensure surfaces are clean and free of debris to get an accurate reading.

Usage recommendations

Store the square flat or hung by its stock to prevent bending. Keep edges clean and free from chips; if necessary, remove light burrs with a fine file or abrasive to restore straightness. Avoid using the tool as a lever or striking surface to preserve squareness and accuracy.
