Level Stanley 1-43-548 1.2 m Yellow

The Stanley 1-43-548 level is a 1.2 m aluminium spirit level finished in high-visibility yellow. It delivers a stated leveling accuracy of ±0.5 mm/m and is designed for general measuring and alignment tasks in construction, carpentry and home renovation. The tool’s length provides a balance between portability and stability for longer straight edges and flatness checks.

Advantages

This Stanley level combines a rigid extruded frame with clear vial markings for reliable repeatable readings. The bright yellow finish improves visibility on work sites and in dim conditions. Its 1.2 m length offers extended support for checking evenness across larger surfaces while remaining easy to carry and store. The ±0.5 mm/m accuracy ensures measurements suitable for most professional and DIY applications.

Suitable for

• Checking levelness of floors, walls and countertops
• Aligning door and window frames
• Setting out and verifying straight lines for carpentry and joinery
• General construction and renovation site measurements

Key specifications

• Length: 1.2 m
• Accuracy: ±0.5 mm per meter
• Material: extruded aluminium body
• Finish: high-visibility yellow
• Vial type: spirit (bubble) vial with clear markings

How to use

Place the level on the surface to be measured so the base rests flat against the workpiece. Read the position of the bubble within the vial to determine whether the surface is level or plumb; adjust the object or surface until the bubble centers between the vial marks. For longer spans, position the level at multiple points and compare readings to identify deviations. Use the level’s edge as a straight reference for marking and alignment tasks.

Usage recommendations

Store the level in a dry place and avoid dropping or bending the frame to maintain accuracy. Clean the vials and base before critical measurements and periodically check accuracy against a known straight reference. For the most accurate results, take multiple readings and use shims or adjustments as needed to achieve the required alignment.
