Level STANLEY FM I BEAM 120 cm magnetic (model S/43-556-1)

STANLEY FM I BEAM magnetic level, 120 cm length, offers a long, rigid reference for alignment and levelling tasks. The I-beam profile provides structural stiffness while integrated magnets allow hands-free attachment to ferrous surfaces. The tool is designed to deliver stable horizontal and vertical measurements over extended spans, suitable for construction, metalwork and general installation tasks where a straight, durable edge is required.

Advantages

The I-beam construction reduces deflection and keeps the profile straight during use, improving measurement reliability across the full 120 cm length. Integrated magnets provide secure contact with steel and other ferrous materials for hands-free operation, enabling single-person use in many scenarios. The simple vial layout supports both horizontal and vertical leveling and helps achieve consistent alignment on long runs.

Suitable for

• Aligning and levelling steel beams, pipes and metal frames
• Setting out long level reference lines in construction and renovation
• Installation of shelving, cabinets and fixtures on metal surfaces
• General carpentry and metalworking tasks that require a stable straightedge

Key specifications

• Length: 120 cm
• Profile: I-beam for increased rigidity
• Magnetic: integrated magnets for attachment to ferrous surfaces
• Vials: orientation for horizontal and vertical leveling
• Primary use: construction, installation and metalwork measuring

How to use

Place the STANLEY I BEAM level against the surface to be checked and allow the integrated magnets to secure it in position if the surface is ferrous. Observe the vial for bubble centring to determine horizontal or vertical alignment. For non-ferrous surfaces, hold or clamp the level along the required line and read the vials while making adjustments. Use the long, stiff profile as a straightedge for transferring lines or checking runout across extended spans.

Usage recommendations

Store the level in a dry place and avoid impacts to protect vial accuracy. When using magnetic attachment, verify that the level sits flat against the workpiece and clean contact surfaces of debris or paint to ensure full magnetic contact. Periodically check vial accuracy against a known reference and recalibrate or replace the tool if measurements deviate beyond acceptable tolerance for your application.
