The Stanley FatMax® Xtreme level has solid-block acrylic vials to provide an accuracy of 0.5mm/m in eight orientations. In addition, every FatMax Xtreme level comes with a lifetime accuracy warranty. The level is 5 times stronger than other Stanley levels, thanks to its unique reinforced box-beam construction. The lightweight aluminium body and sturdy bi-material handgrips make handling easy and the precision engineered, dual-machined levelling surfaces ensure maximum accuracy. The vials are magnified by 20% for improved all round visibility, and the shock absorbing end caps protect the level even if it is dropped.
