Level STANLEY STHT1-43115 1.5 m aluminium with 0.5 mm/m accuracy

Rigid aluminium spirit level STANLEY STHT1-43115, 1.5 m length with levelling accuracy ±0.5 mm/m, designed for professional and DIY measuring tasks. The tool combines a lightweight yet robust aluminium profile with integrated vials for horizontal and vertical alignment, providing reliable straightness checks and fixture positioning on construction sites, in carpentry workshops, and during installations.

Advantages

The aluminium construction ensures a balance of low weight and structural stiffness, making the level easy to handle over extended use while resisting bending. Built-in high-contrast vials offer clear bubble visibility for accurate measurements in both horizontal and vertical orientations. The 1.5 m length covers most common levelling spans and the specified accuracy of ±0.5 mm/m supports precise alignment when installing fixtures, frames or checking surfaces. The profile ends and enclosed vial mounts increase durability for on-site use.

Suitable for

• General construction levelling and layout
• Carpentry and joinery tasks such as door and window installation
• Plumbing, radiator and sanitary fixture alignment
• DIY projects and interior finishing work
• Checking straightness of long surfaces and frames

Key specifications

• Length: 1.5 m
• Material: aluminium profile
• Levelling accuracy: ±0.5 mm per metre
• Vials: horizontal and vertical integrated spirit vials with high-contrast markings
• Weight: lightweight design for easier handling (manufacturer typical construction)
• Construction: rigid closed-profile for increased stiffness and durability

How to use

Place the level on the surface or against the object to be aligned. For horizontal measurements, set the level on the intended plane and observe the central vial; adjust the object until the bubble centers between the markings. For vertical alignment, orient the level against the upright surface and use the vertical vial in the same manner. For longer spans, measure from multiple positions along the run to verify straightness and continuity. Handle the tool by its profile to avoid disturbing the vials and store it flat to maintain calibration.

Usage recommendations

Inspect vials and profile before use; clean contact surfaces to avoid debris affecting accuracy. Avoid dropping or striking the level to preserve vial alignment. Store in a dry place and avoid prolonged exposure to extreme temperatures to maintain material and vial performance.
