Mason's straightedge PRO 250 cm with integrated spirit level, model 3-01-02-19-250

PRO mason's straightedge 250 cm with integrated spirit level, model 3-01-02-19-250, is a rigid leveling rule designed for masonry and plastering tasks. At 250 cm length it provides a long, stable reference for screeding, aligning masonry units and checking surface flatness on walls and façades. The integrated bubble vial helps monitor horizontal alignment without the need for a separate level, while the straightedge's stiff construction resists bending during use.

Advantages

The straightedge combines a long measuring surface with an integrated spirit level to simplify layout and leveling operations. Its length covers large sections of wall or plaster in one pass, reducing the number of joints and transitions compared with shorter rules. The integrated vial offers quick visual confirmation of horizontal alignment, and the straight, rigid profile ensures consistent contact with the substrate for reliable flatness checks.

Suitable for

• Leveling and screeding plaster on interior and exterior walls
• Aligning and checking masonry blocks, bricks and panels
• Checking flatness and continuity of façades and render
• Preparing surfaces before tiling or other finishing work

Key specifications

• Overall length: 250 cm
• Type: straight masonry straightedge with integrated spirit level
• Main function: long leveling rule for screeding and flatness checks
• Construction: rigid profile designed to resist bending under normal use
• Included leveling aid: bubble vial for horizontal alignment

How to use

Place the straightedge across the work surface so the bottom edge contacts the plaster or masonry. Use the integrated spirit level to check horizontal alignment and adjust the material or supports until the bubble is centered. For screeding, move the straightedge along the surface with a sawing or dragging motion to remove excess material and create a flat, even plane. When checking alignment of blocks or tiles, rest the straightedge on reference points and inspect gaps along the edge to detect deviations.

Usage recommendations

Store the straightedge on a flat surface or hang it to avoid warping. Clean off mortar or plaster residues after use to maintain accurate contact with the surface. For best results use with stable reference points and supports; avoid applying excessive force that could deform the profile.
