The Stanley FatMax™ Pro level has solid-block acrylic vials to provide an accuracy of 0.5mm/m in eight orientations. In addition, every FatMax Pro level comes with a lifetime accuracy warranty.
Compared to other Stanley levels this one is 5 times stronger. This is becuase it has a 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% which results in improved all round visibility, also the shock absorbing end caps protect the level even if it is dropped.
