Aluminum Carpenter Square JOBIprofi 300 mm model W13330

JOBIprofi Aluminum Carpenter Square model W13330 is a 300 mm right-angle measuring tool designed for carpentry, woodworking and joinery. Made from rigid, lightweight aluminum, this square provides a stable reference edge for marking, checking squareness of parts and assemblies, and guiding saw or chisel cuts. Its compact 300 mm leg length makes it convenient for use on-site and in workshop benches where accuracy and portability are required.

Advantages

The aluminum construction offers a balance of strength and low weight, resisting deformation during normal use and transport. A precisely machined right angle ensures reliable squareness checks and repeatable layout work. The compact dimensions allow easy handling in tight spaces and quick alignment against edges. Corrosion-resistant surface treatment contributes to long-term dimensional stability and minimal maintenance.

Suitable for

• Marking and laying out right angles on wood and sheet materials
• Checking squareness of frames, cabinets and assemblies
• Guiding straight cuts and positioning saw blades or chisels
• Portable use on construction sites and workshop benches

Key specifications

• Material: aluminum alloy with protective surface finish
• Leg length: 300 mm
• Shape: fixed 90° carpenter's square
• Weight: lightweight design for easy handling
• Durability: resistant to bending under normal carpentry use

How to use

Place the longer leg of the square firmly against the reference edge of the workpiece and press the shorter leg flat onto the face to mark a perpendicular line. Use a sharp pencil, knife or marking scribe along the outer edge to transfer the layout. To check squareness, align the square against adjoining edges or faces and observe any light gaps or misalignment; reverse the square and recheck to confirm results. When guiding a saw or chisel, hold the square steady and use its straight edge as a fence or visual guide while cutting.

Usage recommendations

Store the square flat or hung on a tool board to avoid accidental bends. Clean debris from the edges before making precision marks. For highest accuracy, periodically check the right angle against a calibrated reference or a known square; avoid using excessive force that could deform the aluminum.
