Spirit Level STANLEY 180° I-Beam Level 1-42-923

The STANLEY 180° I-Beam Level 1-42-923 is a precision hand level designed for checking horizontality, verticality and a wide range of angles on construction, carpentry and DIY projects. Its I-beam aluminium profile provides rigidity and stability while the long straight edges assist in aligning surfaces and fixtures. The tool combines three bubble vials — a top read level vial, a plumb vial and a 180° rotating angle vial with double graduation — to offer quick, reliable visual indication of orientation and angle.

Advantages

The aluminium I-beam body delivers strength and long-term dimensional stability while remaining lightweight for handheld use. Three tubular vials enable measurement of level, plumb and angles up to 180° with clear graduations, and the stated accuracy of ±1.5 mm/m supports precise alignment tasks. Shock-absorbing end caps protect the vials and maintain accuracy if the level is dropped. Multiple length options allow selection of the working span that best fits the task.

Suitable for

• General carpentry and joinery work
• On-site construction levelling and layout
• Installing cabinets, shelves, doors and windows
• Workshop projects and furniture assembly
• DIY home renovation and finishing tasks

Key specifications

• I-beam aluminium profile for rigidity and reduced flex
• Three tubular vials: top read level, plumb and 180° rotating angle vial with double graduation
• Accuracy: ±1.5 mm/m
• Shock-absorbing end caps for impact protection
• Available lengths: 400 mm, 600 mm, 800 mm, 1000 mm, 1200 mm
• Long straight edges for alignment and scribing

How to use

Place the level on the surface to be checked: rest the long edge along the workpiece for horizontal checks or place the narrow edge against a vertical surface for plumb verification. Read the bubble position in the appropriate vial — top read for horizontality, plumb for verticality and the rotating angle vial for 180° measurements and intermediate angles. For more accurate alignment, adjust the workpiece until the bubble is centered between the vial’s marking lines. Use the long straight edge as a guide for marking or transferring level lines.

Usage recommendations

Store the level in a dry place and avoid prolonged exposure to extreme temperatures or solvents. Inspect vials and end caps regularly for damage; replace the tool if vials are cracked or bubbles are not stable. Select the length that suits the span of your work to reduce the need for multiple setups and to improve measurement reliability on-site.
