The Stanley FatMax XTREME Box Beam Level is built for durability, precision, and performance on every job. Its patented continuous edge allows for uninterrupted scribing along the full length, while the finely milled primary edge delivers 0.5mm/m accuracy and a secondary edge offers 0.8mm/m. Engineered for resilience, it features fully secured vial technology to protect against drop damage, and a 90% larger plumb vial for improved bubble visibility. Shock-absorbing rubber end caps safeguard the level from impact and include raised anti-slip protectors to prevent surface marking. Removable end caps make 90-degree markings and corner lines easier and more accurate. Designed with ergonomics in mind, the level includes strategically placed finger rails and wraparound grips for comfortable, one-handed use.
