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. 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 ends protect the level even if it is dropped. The Stanley STA 0-43-609 FatMax Torpedo level is 10 inches in length with 3 vials and has a V groove machined in the magnetic base, which allows it to fit firmly on pipe work, ideal.
