Steel Carpenter's Square Koelner MN-83-014 160×350 mm

Koelner steel carpenter's square MN-83-014 with blade dimensions 160×350 mm is a right-angle measuring and marking tool designed for woodworking, metalworking and construction layout. Made of steel, it provides a stable, accurate 90° reference for marking, checking squareness of edges and joints, and transferring measurements between workpieces. The compact dimensions make the square convenient for workshop benches and on-site use where reliable squareness control is required.

Advantages

The steel construction ensures rigidity and resistance to bending during repeated use, while the flat blades provide a consistent reference surface for accurate marking and checking. Its size balances portability with a usable blade length for a variety of tasks. The simple, open-frame design allows direct contact with surfaces for clear scribing and measurement transfer.

Suitable for

• Checking and marking 90° angles on timber and sheet materials
• Verifying squareness of joints, frames and furniture components
• Transferring measurements from one workpiece to another
• Use in workshops, construction sites and metalworking benches

Key specifications

• Material: steel
• Blade dimensions: 160 × 350 mm
• Type: carpenter's square (right-angle)
• Reference angle: 90°
• Finish: plain steel surface suitable for scribing and measuring

How to use

Place the inner corner of the square against the edge or reference face of the workpiece so that both blades lie flat. For marking, hold the stock firmly against the edge and scribe along the blade with a pencil or marking knife to transfer the 90° line. To check squareness, align one blade with the known face and inspect the opposite edge for gaps or light indicating deviation. Use the blade lengths to transfer measurements by laying the square across the workpiece and marking at the required distance.

Usage recommendations

Store the square on a flat surface or hang it to avoid bending; keep the blades clean and free of burrs for accurate contact. For the best results when marking, use a sharp pencil or knife and verify squareness periodically with a calibrated reference if precision is critical.
