Spirit level Proline 15937 — length 1.5 m

Proline 15937 — length 1.5 m is a 1.5 metre spirit level designed for accurate straightness and alignment checks in construction, installation and renovation work. The long profile provides a stable reference when checking horizontals and verticals on walls, frames, doors and large fixtures. Built with a durable aluminium body and a milled measuring edge, the tool balances portability with the extended reach required for carpentry, masonry and general DIY tasks.

Advantages

The level features a precise measurement accuracy of 0.5 mm per metre and three high-quality vials with a lifelong guarantee, ensuring reliable readings for horizontal, vertical and 45° checks. Its powder-coated aluminium body resists corrosion and wear while keeping the tool lightweight. A milled measuring edge increases contact stability and prevents slipping on flat surfaces. An integrated holder allows convenient hanging for storage and on-site organization.

Suitable for

• Aligning walls, partitions and large panels
• Checking door and window frames during installation
• Carpentry tasks such as installing cabinets and shelves
• Masonry and tiling work requiring long straight references
• General DIY projects that need accurate long-span leveling

Key specifications

• Length: 1.5 m profile for extended reach and stability
• Measurement accuracy: 0.5 mm per metre
• Vials: three high-quality level vials with lifelong guarantee for horizontal, vertical and 45° readings
• Body: high-quality aluminium, powder-coated for corrosion resistance
• Measuring edge: milled edge for secure contact on flat surfaces

How to use

Place the spirit level against the surface to be checked, ensuring full contact along the milled edge. For horizontal checks, orient the appropriate vial and read the bubble position; for vertical or 45° checks, use the corresponding vial. When measuring over longer spans, support the level at intermediate points if necessary to avoid sagging. After use, hang the level by its holder to keep the vials protected and the measuring edge straight.

Usage recommendations

Store the spirit level in a dry place and avoid impacts that could misalign the vials. Clean the milled edge before critical measurements to ensure full contact. Periodically verify accuracy against a known reference surface, especially after drops or heavy use.
