Stanley STA143676 FATMAX Xtreme Box Beam Level 120cm

For longer runs and extended alignment tasks, precision must remain consistent from end to end. The Stanley STA143676 FATMAX Xtreme Box Beam Level 120cm is engineered for tradespeople who require exceptional durability and reliable accuracy across larger surfaces such as stud walls, kitchen installations, flooring, brickwork, and structural framing.

The reinforced box beam construction offers superior strength compared to traditional I-beam levels, helping maintain calibration even under tough job site conditions. Its fine milled primary measuring edge provides an impressive 0.5mm per metre accuracy, while the secondary edge maintains 0.8mm per metre accuracy, ensuring dependable results whether checking horizontal or vertical alignment.

A standout feature is the patented continuous edge, allowing users to draw or scribe uninterrupted lines along the entire 120cm length. This is particularly valuable for marking timber, plasterboard lines, cabinetry layouts, and partition installations where clean, straight reference lines are essential.

Stanley’s fully secured vial technology protects the internal vials against impact damage from accidental drops. The 90% larger plumb vial significantly improves bubble visibility, making vertical readings clearer and faster, even in low-light environments.

Durability is further enhanced with shock-absorbing rubber end caps, moulded to protect against impact damage. These caps also feature raised anti-slip surface protectors to prevent slipping and reduce marking on finished surfaces. The removable end caps enable more precise 90-degree corner marking and scribing directly into tight spaces.

Ergonomic improvements include strategically placed finger grab rails and wrap-around hand grips, allowing comfortable one-handed use and improved control during extended measuring sessions.

Ideal for professional builders, carpenters, kitchen fitters, and installers, the FATMAX Xtreme 120cm level combines long-span precision with jobsite durability.
