Spirit level STANLEY Fatmax II 90 cm, 3 vials, accuracy 0.5 mm/m

The STANLEY Fatmax II 90 cm spirit level provides a 90 cm straight profile with three viewing vials for horizontal, vertical and 45° measurements. Engineered for alignment and levelling tasks in construction, carpentry and installation work, the tool combines a rigid aluminium profile with durable end caps and clear acrylic vials. The specified accuracy of 0.5 mm/m ensures precise readings for general professional and DIY use where reliable flatness and plumb are required.

Advantages

The profile construction delivers straightness and resistance to bending during typical on-site use. Three vials give immediate reference for horizontal, vertical and 45° angles without changing the tool orientation. The vials are clear and easy to read, supporting accurate placement and faster checks. Durable end caps and a robust body are intended to withstand frequent handling and transportation on job sites.

Suitable for (tasks / use cases)

• Leveling walls, floors and ceilings during construction and renovation
• Checking plumb for door and window frames
• Aligning cabinets, worktops and shelving in carpentry and joinery
• Setting fixtures and equipment during installations

Key specifications

• Length: 90 cm
• Number of vials: 3 (horizontal, vertical, 45°)
• Accuracy: 0.5 mm per metre
• Profile material: rigid aluminium body
• Vial material: clear acrylic for easy reading

How to use

Place the spirit level on the surface to be checked, ensuring full contact along the profile. For horizontal measurements, position the level on the horizontal plane and read the central bubble in the horizontal vial; for vertical checks, align the level against the vertical surface and read the vertical vial; for 45° angles, use the dedicated 45° vial. If required, rotate the level end-for-end to confirm consistent readings and detect any profile deformation. Clean the contact edges and vials before precision work to avoid reading errors due to debris.

Usage recommendations

Store the level in a protective pouch or toolbox to avoid impacts that could affect accuracy. Periodically verify accuracy against a reference surface, especially after heavy knocks or prolonged use. Avoid exposing the tool to extreme temperatures or chemical solvents that can damage vials or seals.
