Carpenter's Square Grot 350 mm G-400-0635 — metal right-angle measuring tool

Grot 350 mm Carpenter's Square (model G-400-0635) is a metal right-angle measuring tool intended for woodworking and carpentry tasks that require accurate 90° references. The 350 mm length offers a stable straight edge for marking, squaring joints, checking right angles and guiding saw or router paths. Constructed from metal, the square is designed to resist deformation during normal workshop use and to deliver consistent measurements across repeated operations.

Advantages

This metal carpenter's square provides a true 90° reference with a durable straight edge that supports precise layout and verification work. Its 350 mm size balances portability with sufficient length for marking larger panels and framing components. The rigid construction reduces flex and wear, while the clean edge ensures accurate scribing and reliable contact against workpieces.

Suitable for

• Squaring and aligning furniture parts and cabinet components
• Marking right angles on timber, plywood and MDF panels
• Verifying the squareness of joints and assembled frames
• Guiding handsaw or router cuts along a straight reference

Key specifications

• Material: metal construction for rigidity and wear resistance
• Overall length: 350 mm straight edge for layout and marking
• Angle accuracy: manufactured to provide a reliable 90° reference
• Edge type: machined straight edge suitable for scribing and guiding tools
• Application: designed for woodworking, joinery and general workshop use

How to use

Place the inside corner of the square firmly against the mating faces of the workpiece to establish a 90° reference. Use the straight edge to scribe lines for cutting or to check alignment by observing any gaps between the square and the material. For marking, hold the square steady with one hand and run a pencil or marking knife along the outside edge to transfer the line. For verification, rotate and recheck opposite corners or mating edges to confirm consistent squareness across the assembly.

Usage recommendations

Store the square in a dry place and avoid subjecting the edge to shocks or drops that could deform the straight edge. Clean sawdust and resin from the edge after use to maintain accuracy. When precise calibration is required, compare the square against a known reference or use a precision try square before critical measurements.
