SOLA Carpenter's Square SRB 300 300×145 mm, stainless steel

The SOLA Carpenter's Square SRB 300 (300×145 mm) is a stainless steel layout square engineered for accurate squaring, marking and measuring in woodworking and general construction. Its solid stainless steel body offers straight, wear-resistant edges for transferring right angles, checking mitres and scribing precise cutting lines. The compact dimensions combine portability with enough length for common carpentry tasks, making it suitable for workshop benches and on-site use.

Advantages

The stainless steel construction resists corrosion and maintains straightness over time, ensuring repeatable accuracy. Precisely ground edges provide reliable reference lines for marking and cutting. The 300×145 mm format balances measuring reach and compact handling, while a rigid, single-piece design reduces the risk of flexing during layout work. The tool's surface is easy to clean and remains dimensionally stable under normal workshop conditions.

Suitable for

• Measuring and marking right angles in timber framing and joinery
• Checking squareness of boards, panels and assemblies
• Scribing cutting and saw guide lines for panel work and trim
• General layout tasks on-site and in the workshop

Key specifications

• Material: stainless steel for corrosion resistance and durability
• Overall dimensions: 300 × 145 mm for compact layout and marking
• Edges: straight, ground edges for accurate marking and measurement
• Design: rigid, single-piece construction to minimise flexing
• Finish: smooth, easy-to-clean surface suitable for precise layout work

How to use

Place the SOLA SRB 300 with one leg firmly against the workpiece to establish a reference edge, then use the opposite leg to mark a 90° line with a pencil or scribe. For checking squareness, hold the square against two adjoining faces and observe any gap or light to identify misalignment. Use the straight edge as a saw guide for short cuts or to transfer lines across panels. Ensure the square is clean and free of debris before measuring to maintain accuracy.

Usage recommendations

Store the square in a dry location and avoid dropping or bending it to preserve straightness. Wipe off adhesives, paint or wood dust after use and periodically check edge integrity on a known straight surface. For critical layout tasks, verify accuracy against a calibrated reference tool before use.
