Mason’s Straightedge PRO 250 cm with Vertical and Horizontal Indicator (model 3-01-02-20-250)

PRO mason’s straightedge 250 cm (model 3-01-02-20-250) is a long leveling and alignment tool with an integrated vertical and horizontal indicator. Designed for masonry, plastering and façade work, the straightedge provides a stable, straight reference edge across large surfaces to check and correct deviations. Its 250 cm length allows accurate alignment of walls and screeds and simplifies verification of plumb and level over extended spans on construction and renovation sites.

Advantages

The straightedge combines a durable extruded profile with a built-in vertical and horizontal indicator to deliver reliable measurements without the need for separate spirit levels. Its length reduces the number of reference points required and helps identify waves or unevenness in a single pass. The integrated indicators are positioned for easy reading while the profile offers a rigid, torsion-resistant edge suitable for repeated on-site use.

Suitable for

• Wall leveling and alignment for masonry and block work
• Plaster and render straightening over long runs
• Screed and floor screed verification for flatness and slope
• Façade alignment and exterior surface checks

Key specifications

• Length: 250 cm effective working edge suitable for long spans
• Built-in vertical and horizontal indicator for plumb and level checks
• Material: rigid extruded profile designed for minimal torsion
• Profile edge: straight reference surface for scraping and straightening
• Weight: balanced for handheld use across extended distances

How to use

Place the straightedge against the surface to be checked, aligning its edge with the reference line or base. Read the integrated horizontal or vertical indicator to determine deviations from level or plumb, then move along the surface to check consistency over the full 250 cm span. For leveling screeds or straightening plaster, use the straightedge as a guide to scrape across the surface, removing high spots and filling low areas until the indicator shows the desired alignment. Handle the tool with two hands on longer passes to maintain even pressure and reduce flexing.

Usage recommendations

Store the straightedge on a flat surface or hang it by its mounting points to avoid bending. Clean abrasive residue after use and inspect the indicator periodically for correct calibration. For most wall and screed tasks, pair the straightedge with a shorter level or laser for fine adjustments in confined areas.
