Spirit level board STABILA AL1L, 200 cm length

STABILA AL1L spirit level board, 200 cm length, is a rigid straight edge designed for leveling, aligning and transferring reference lines on construction and woodworking sites. Its 200 cm span provides a long, stable reference surface for checking flatness, setting screeds, aligning formwork and verifying level over larger distances. The profile is engineered to resist bending under normal working loads and to maintain a reliable datum when used with masonry, concrete, flooring and finishing tasks.

Advantages

The STABILA AL1L combines a long, rigid profile with precise straightness to deliver consistent reference across its entire length. Its construction reduces flexing during use, improving accuracy when checking planarity or transferring levels. The board’s length simplifies work on larger surfaces by reducing the need to join shorter straight edges, and its durable design is suited to frequent on-site handling.

Suitable for

• Checking and transferring level across flooring and screeds
• Aligning and setting masonry and concrete formwork
• Verifying straightness of panels, worktops and large carpentry elements
• Smoothing and striking off plaster or cement renders

Key specifications

• Length: 200 cm usable straight-edge span
• Profile: rigid, straight-edge construction for reduced flex
• Primary use: long reference surface for leveling, alignment and flatness checks
• Suitable materials: masonry, concrete, flooring, plaster and woodwork

How to use

Place the STABILA AL1L spirit level board on the surface to be checked or used as a screed guide, ensuring full contact along the length where possible. Use the board to transfer a datum by aligning it with an established level point, then move along the working area to mark or correct high and low spots. For striking off plaster or screed, draw the board along the surface with steady, even pressure to achieve a flat finish. When checking straightness of panels or worktops, rest the board across the piece and inspect gaps or light passage along the edge to identify deviations.

Usage recommendations

Store the board on a flat surface or hang it to avoid long-term bending. Inspect before use for dents or damage that could affect straightness, and clean contact faces of debris to maintain accuracy. For repetitive precision tasks, combine the board with a spirit level or laser reference to confirm alignment over long distances.
