PRO construction corner square 600 x 1200 mm painted model 402-12

PRO construction corner square 600 x 1200 mm painted model 402-12 is a metal layout and measuring tool designed to establish and check precise 90° angles and straight edges on building sites and in workshops. With large dimensions of 600 x 1200 mm and a painted finish, this square provides a clear, durable surface that resists wear during masonry, carpentry and installation work. The rigid construction ensures consistent squareness for setting out, marking and verifying alignments on frames, walls and panels.

Advantages

The painted surface improves visibility of markings and helps protect the metal from minor corrosion and scratches. Large-format legs allow quick checking over extended spans without the need for multiple small tools. The rigid, stable frame maintains a true 90° angle under normal working loads, reducing the need for repeated measurements and adjustments. Its size makes it suitable for both on-site use and workshop layout tasks where accurate right-angle references are required.

Suitable for

• Masonry layout and corner checking
• Carpentry and timber framing alignment
• Installation of cladding, drywall and panels
• Fabrication and workshop marking of large components

Key specifications

• Overall dimensions: 600 x 1200 mm
• Material: metal construction
• Finish: painted surface for improved visibility and protection
• Shape: fixed right-angle (90°) corner square
• Intended use: layout, marking and squareness verification on large-format elements

How to use

Place the square with its inner corner against the junction or corner to be checked so both legs make full contact with the surfaces. For marking, align the edge with the intended cut or joint and scribe along the leg using a pencil or marker. To verify squareness, position the square on each adjoining face and confirm there are no gaps between the tool and the workpiece; if gaps appear, adjust the workpiece or structure until full contact is achieved. Use a flat, stable support and keep the painted surface clean from heavy debris to maintain accuracy.

Usage recommendations

Store the square flat or hung by a dedicated hanging point to prevent bending. Clean off mortar, paint or adhesives after use and inspect the edges periodically for nicks or deformities; damaged edges can affect squareness and should be repaired or replaced.
