Aluminium construction square Dedra ML2064 500 x 225 mm, right-angle measuring tool

Dedra ML2064 500 x 225 mm is an aluminium construction square designed to provide precise right-angle layout and measurement on a variety of building materials. Its 500 mm by 225 mm dimensions make it suitable for marking and checking 90° corners on boards, panels, frames and masonry. The aluminium construction offers a balance of light weight and corrosion resistance for frequent on-site use.

Advantages

The construction square combines a rigid profile with low weight, enabling accurate measurements without excessive bulk. Corrosion-resistant aluminium reduces maintenance and preserves measurement accuracy over time. Its clear flat edges provide reliable reference surfaces for scribing, marking and checking squareness during carpentry, framing and general construction work.

Suitable for

• Carpentry layout and marking of boards and panels
• Checking squareness of frames and assemblies
• Setting out masonry and tiling right angles
• General construction and renovation tasks requiring 90° measurements

Key specifications

• Material: aluminium alloy construction for reduced weight and corrosion resistance
• Dimensions: 500 mm x 225 mm overall measuring faces
• Right-angle design: fixed 90° reference for layout and verification
• Edges: flat straight edges suitable for scribing and marking
• Weight: lightweight design for handheld use and portability

How to use

Place the square so both faces sit flat against the two surfaces that form the corner to be measured or marked. Ensure the reference edges are clean and true, then mark along the edge with a pencil or scribe for accurate layout lines. To verify squareness of an assembly, press the square into the corner and check for gaps or light between the tool and the workpiece; any gap indicates deviation from 90° that can be corrected before fixing components.

Usage recommendations

Store the aluminium square in a dry place and keep the edges free of nicks and burrs; light filing of minor burrs will restore a clean marking surface. Use in combination with a straightedge or spirit level for complex layouts, and protect the tool from heavy impacts that could deform the edges and affect measurement accuracy.
