The Stanley FatMax 1-43-549 is a 120cm magnetic spirit level with three vials and an accuracy of 0.5mm/m in normal working position. At 120cm this is the standard full-length level for general construction work: wall runs, floor screeding, stud walls, suspended ceilings, and any task where accuracy over a longer span matters. The 4-foot length has been the trade standard for decades because it bridges enough distance to catch deviations that shorter levels miss.

Rare earth magnets in the base hold the level firmly against steel framing, lintels, and other ferrous surfaces, leaving both hands free for adjustment and marking. The reinforced aluminium box-beam body resists the twisting and bowing that cheaper levels suffer from, and the dual-machined levelling surfaces provide consistent, reliable contact with the work surface. Solid block acrylic vials are magnified for easier reading and are bonded securely to maintain accuracy through repeated impacts.

Bi-material hand grips at both ends provide a comfortable, secure hold for positioning the level overhead or at height. Shock-absorbing end caps protect the frame and vials from drops and knocks on site.
