These are 2 of the most popular and commonly used sizes of level, a 120cm(4ft) and a 60cm(2ft) in a single package offer. The Stanley FatMax Pro Levels are machine-milled top and bottom, ensuring accuracy on both sides. The dual bi-material grips are ideal for carrying and vertical levelling. 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. FatMax Pro Levels provide an accuracy of 0.5mm/m in 8 orientations. In addition, every FatMax™ Pro Level comes with a lifetime accuracy warranty.
