Mason's Straightedge PRO 150 cm with Plumb and Level Indicator (model 3-01-02-20-150)

PRO mason's straightedge 150 cm with integrated plumb and spirit level indicators (model 3-01-02-20-150) is a field tool for checking flatness, verticality and evenness of masonry and plaster surfaces over extended lengths. The straightedge combines a rigid, lightweight beam with built-in plumb and level elements to provide a stable reference when setting, levelling and smoothing mortar or render on walls, floors and other large surfaces.

Advantages

The tool delivers consistent reference alignment across long runs thanks to its 150 cm length and stiff construction, reducing the need for frequent repositioning. Integrated plumb and spirit level indicators allow quick verification of vertical and horizontal alignment without switching tools. Lightweight materials make the straightedge easy to handle on scaffolds or ladders while maintaining sufficient rigidity to resist bending during typical masonry and plastering tasks.

Suitable for

• Bricklaying and blockwork alignment
• Plaster and render levelling on walls and ceilings
• Checking evenness of screeds and floor surfaces
• Layout and verification of vertical plumb lines
• General on-site surface straightening and finishing

Key specifications

• Length: 150 cm working span
• Integrated plumb indicator for vertical checks
• Built-in spirit level for horizontal alignment
• Lightweight, rigid beam construction suitable for on-site use
• Designed for use with mortar, render and screed surfaces

How to use

Place the straightedge against the surface to be checked and slide it along the area to identify hollows, high spots or uneven sections. Use the built-in spirit level to ensure horizontal alignment by adjusting the surface until the bubble centers. For vertical surfaces, align the integrated plumb indicator and adjust block or render positions to achieve true verticality. When levelling mortar or render, use the straightedge as a screeding guide and strike off excess material, then re-check with the level and plumb indicators to confirm evenness.

Usage recommendations

Store the straightedge in a dry place to prevent damage to level vials. Inspect the plumb and spirit indicators periodically for accuracy and secure fit. Use two-person handling for prolonged overhead work or when working on long uninterrupted spans to maintain control and avoid accidental bending.
