Spirit level Proline 15935 — 1 m length, bubble vial leveling tool

Proline 15935 — 1 m length spirit level is a compact leveling tool intended for checking straightness and horizontal or vertical alignment in construction, carpentry and general DIY tasks. The tool features three high-quality bubble vials with a lifelong guarantee and a durable aluminum body with powder coating. A milled measuring edge and a hanger holder increase practicality on-site and during indoor installation work.

Advantages

The spirit level provides an accuracy of 0.5 mm per 1 m, allowing precise alignment of frames, surfaces and installations. Three vials give reliable readings in horizontal, vertical and 45° positions. The high-quality aluminum body is lightweight yet robust and resists corrosion due to the powder-coated finish. The milled edge ensures stable contact with straight edges and profiles, and the integrated holder enables convenient hanging and storage.

Suitable for

• Leveling and aligning door and window frames
• Installing shelves, cabinets and kitchen units
• Checking wall plumb and floor evenness during renovation
• Carpentry and joinery alignment tasks
• General site and workshop measuring where a 1 m level is required

Key specifications

• Length: 1 m
• Measurement accuracy: 0.5 mm / 1 m
• Number of vials: 3 (horizontal, vertical, 45°)
• Body material: aluminum with powder coating
• Milled measuring edge for stable contact
• Integrated holder for hanging and storage

How to use

Place the spirit level on the surface or profile to be checked and observe the position of the bubble within the appropriate vial. For horizontal checks use the horizontal vial; for vertical plumb use the vertical vial; use the 45° vial for angled measurements. If the bubble is centered between the marks, the surface is level or plumb. For longer alignments, mark one end, then slide the level along the line and re-check. Use the milled edge to maintain steady contact with corners and straight profiles.

Usage recommendations

Store the level in a dry place and hang it on the integrated holder to prevent bending or accidental drops. Clean the milled edge and vials after use to remove debris that could affect accuracy. Avoid strong impacts; although the aluminum body is durable, the vials are precision components. Periodically check accuracy against a known straight reference and recalibrate or replace the tool if readings deviate beyond the specified tolerance.
