## Long description

Mason's Straightedge PRO 400 cm with Indicators, model 202-40 is an aluminium straightedge engineered for levelling and aligning masonry, plaster and façade surfaces over long spans. At 400 cm length it provides a rigid guide profile for transferring reference lines, checking flatness and controlling slope. Integrated visual indicators allow quick assessment of inclination and deviations without additional instruments, making the tool practical for on-site layout and finishing tasks.
Advantages
The aluminium construction combines low weight with high stiffness to minimise flexing across the full 4 m length. Integrated indicators give direct visual feedback on slope and flatness, reducing the need for separate spirit levels or laser alignment for many tasks. The straightedge’s long span and straight profile enable consistent reference lines and even material distribution during plastering and rendering. Its durable finish resists routine site wear and simplifies cleaning after use.
Suitable for
Levelling and aligning masonry walls and partitions
Plastering, rendering and smoothing large wall surfaces
Façade work where long straight guides are required
Transferring reference lines and checking plane flatness on construction sites
Key specifications
Length: 400 cm
Material: aluminium profile for reduced weight and high stiffness
Integrated visual indicators for slope and flatness control
Long rigid span suitable for straight reference line transfer
Durable finish for resistance to site wear and easy cleaning
How to use
Place the straightedge across the area to be checked or used as a guide, ensuring end support or temporary props where required to prevent sagging. Use the integrated indicators to observe the slope and flatness; adjust the substrate or application of material until indicators show the desired alignment. For transferring a reference line, align the straightedge with your datum points and mark along the edge. After use, clean off excess material and store the straightedge on a flat surface or hung to preserve its straightness.
Usage recommendations
For best results with the Mason's Straightedge PRO 400 cm, support the tool at intermediate points when spanning long distances to reduce deflection, and verify calibration of the indicators before critical layout work. Use appropriate lifting techniques or a second person when moving or positioning the tool to avoid bending or dropping.
