Level STANLEY STHT1-43102 0.4 m, yellow, accuracy ±0.5 mm/m

The STANLEY STHT1-43102 0.4 m spirit level is a compact measuring tool designed for quick and accurate alignment of horizontal and vertical planes. Its yellow aluminium and plastic construction combines lightweight handling with durability for workshop, on-site, and domestic use. The high-visibility vial allows fast reading of the bubble, and the specified levelling accuracy of ±0.5 mm/m supports fine adjustments during carpentry, installation work and small-scale building tasks.

Advantages

This 0.4 m level offers a balance of portability and precision, making it suitable for confined spaces and rapid checks. The aluminium/plastic body delivers resistance to everyday wear while keeping weight low for comfortable handheld use. A highly visible vial improves readability under various lighting conditions, and the tool’s concise length simplifies handling when measuring short spans or fitting hardware in tight locations.

Suitable for

• Carpentry and joinery tasks
• Installing shelves, cabinets and fittings
• DIY home renovation and repair work
• On-site quick checks and equipment alignment
• Tight or confined measuring spaces

Key specifications

• Length: 0.4 m
• Levelling accuracy: ±0.5 mm/m
• Body materials: aluminium and plastic
• Colour: yellow for high visibility
• Vial: high-visibility bubble vial for fast reading

How to use

Place the level on the surface to be checked and allow the bubble to settle. For horizontal checks, position the tool flat on the surface; for vertical checks, hold it flush against the vertical plane. Adjust the workpiece or fixture until the bubble is centered between the vial markings. For repeatability, verify the reading by rotating the level 180° and rechecking the position; consistent centered readings confirm accurate alignment.

Usage recommendations

Store the level in a dry place and avoid severe impacts to protect vial integrity. Clean contact surfaces before measurement to prevent debris from affecting accuracy. For best results in critical installations, combine this short 0.4 m level with a longer level or laser tool to verify longer spans.
