Plumb and Level Mason's Straightedge 250 cm — PRO brand model 3-01-02-20-250

PRO Plumb and Level Mason's Straightedge 250 cm (model 3-01-02-20-250) is a 2.5-metre aluminium straightedge designed for checking plumb and level and for smoothing and aligning rendered or masonry surfaces. The long rigid profile provides a true reference edge for verifying verticality and horizontality, transferring lines, and striking off excess material on walls, floors and large plastered surfaces. The tool is intended for use on construction sites and renovation projects where length, stiffness and a flat working face are required.

Advantages

The aluminium construction offers a combination of low weight and rigidity for easier handling on scaffolding and ladders while maintaining a straight working edge. Its full-length profile reduces deflection over spans typical in masonry and plastering tasks. The flat face is suitable for striking off wet plaster or mortar and for using as a guide when checking levels and plumb. The straightedge's length provides accurate reference over large surfaces, reducing the need for repeat measurements and improving workflow efficiency.

Suitable for

• Checking and transferring plumb lines on walls and partitions
• Verifying horizontality across long runs and floors
• Smoothing, striking off and levelling plaster, render or mortar
• Aligning blocks, bricks and large-format tiles during installation
• Use on construction sites and renovation projects where a long rigid edge is required

Key specifications

• Length: 250 cm overall usable straight edge
• Material: extruded aluminium profile for reduced weight and increased stiffness
• Cross-section: rigid flat face suitable for striking off and alignment
• Weight: lightweight design for manual handling and positioning
• Durability: corrosion-resistant aluminium surface suitable for site conditions

How to use

Place the straightedge against the surface to be checked or levelled so that the flat face bears evenly along the span. For plumb checks, align the edge vertically and use an appropriate plumb reference or spirit level to confirm verticality; adjust the surface as needed. For levelling and striking off, rest the straightedge on screeds, guides or masonry courses and move it along the surface to remove excess mortar or plaster while maintaining consistent contact. Use two-person handling for long spans or when working from elevated positions to keep the profile straight and safe.

Usage recommendations

Keep the straightedge clean and free of hardened mortar or plaster to preserve a true working face. Store the tool horizontally on supports or hang it to avoid bends. When measuring long surfaces, combine the straightedge with a spirit level or laser for improved accuracy, and use protective gloves when handling on site.
