Spirit level Proline 15936 — 1.2 m length, measuring tool

Proline 15936 — 1.2 m length spirit level is a measuring tool designed for straightness and alignment checks in construction and DIY tasks. The 1.2 m rigid aluminium body provides a stable straightedge for checking horizontal and vertical planes across a longer span, suitable for installing shelves, frames and doors or for general measuring tasks requiring consistent accuracy over metre-plus distances.

Advantages

The level features a high-quality powder-coated aluminium body that resists corrosion while remaining lightweight for easy handling. Three precision vials with a lifelong guarantee deliver reliable readings for horizontal, vertical and 45° angles. A milled measuring edge ensures a true straight reference and enhances durability during repeated use. An integrated holder allows convenient hanging and storage on-site or in a workshop.

Suitable for

• Installing shelves, cabinets and wall-mounted furniture
• Aligning door and window frames
• Level checks on plastering, tiling and carpentry over long spans
• General construction, renovation and DIY measurement tasks

Key specifications

• Length: 1.2 m
• Measurement accuracy: 0.5 mm per 1 m
• Vials: three high-quality level vials (horizontal, vertical, 45°) with lifelong guarantee
• Body: aluminium, powder coated
• Measuring edge: milled straight edge for precise alignment
• Mounting: integrated holder for hanging and storage

How to use

Place the spirit level on the surface to be checked so the milled edge rests firmly against the material. Read the appropriate vial for horizontal, vertical or 45° alignment and adjust the element until the bubble centers between the vial markings. For longer spans, take multiple measurements along the run to confirm consistent straightness. After use, hang the level by its holder to protect the vials and straight edge from damage.

Usage recommendations

Keep the milled edge clean and free of debris to maintain measurement accuracy. Avoid dropping the level or striking the vials directly. Store in a dry place and verify accuracy periodically if used frequently in demanding site conditions.
