The Stanley FatMax Pro level has solid-block acrylic vials to provide an accuracy of 0.5mm/m in eight orientations. 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.
