The Stanley FatMax 1-43-537 is a 90cm magnetic spirit level with three vials and an accuracy of 0.5mm/m in normal working position. The 90cm length sits between the shorter torpedo levels and the full-size 120cm, making it practical for door frames, window reveals, kitchen unit runs, and mid-range levelling work where a 120cm level would be too long to manoeuvre comfortably.

Rare earth magnets in the base hold the level securely to steel lintels, metal stud framing, and ferrous surfaces, freeing both hands for marking or adjusting. The aluminium box-beam construction is reinforced for impact resistance, and the dual-machined levelling surfaces are precision ground for consistent contact with the work surface. Solid block acrylic vials are magnified for improved readability and are bonded into the frame to maintain their accuracy even after repeated drops.

Bi-material hand grips on both ends provide a secure hold during positioning and make the level easier to manoeuvre overhead or at awkward angles. Shock-absorbing end caps protect the level body from the inevitable impacts of daily site use without transferring force to the vials.
