The Stanley FatMax 0-42-086 is a 120cm digital spirit level with three vials and an integrated digital angle readout. The 120cm (4ft) length is the standard for full-size levelling work on walls, floors, and structural elements where the longer reference surface produces more accurate readings across wider spans.

The digital display provides angle readings in degrees, which matters when setting precise falls on screed, checking wall plumb to tight tolerances, and verifying that structural steelwork meets specification. The backlit screen is readable in the low-light conditions common on construction sites, from ceiling voids to basement conversions. The digital sensor works independently of the three bubble vials, so you get both a quick visual check and a precise numerical reading from the same tool.

The FatMax aluminium frame is designed for the demands of daily site use. At 120cm the level spans door openings, kitchen runs, and wall sections in a single placement, reducing the cumulative error that comes from stepping a shorter level along a surface. The frame resists bowing under its own weight, which is essential for accuracy at this length.

Three vials cover horizontal, vertical, and 45-degree orientations. The horizontal vial handles floor screeds and worktops, the vertical vial covers stud walls and door frames, and the 45-degree vial is used on pitched roofwork and staircase stringers.
