Bosch GLL50-20G Green-beam Self-leveling Cross-line Laser

Product Description

The ROBERT BOSCH TOOL GROUP GLL50-20G is a green-beam self-leveling cross-line laser designed for layout and alignment tasks in construction and trade applications. It projects two bright, level and plumb green beams with a working range of up to 65 feet. Green-beam output is up to 4X brighter than standard red beams, improving visibility in well-lit jobsite conditions. The unit runs on included AA batteries or an optional Bosch 3.7 volt Lithium-Ion 1.0 Ah battery that can be used while charging. Built-in VisiMax Technology automatically optimizes line brightness and runtime based on working conditions. The tool weighs 9.25 pounds and carries an IP55 dust and water-resistance rating.

The GLL50-20G is suited for residential and light commercial construction work including leveling, plumbing, squaring, and layout tasks. Licensed contractors, finish carpenters, tile setters, and electricians use this type of tool when establishing reference lines across walls, floors, and ceilings. Its compact, ergonomic form factor makes it practical for confined spaces and elevated work surfaces. The full rubber overmold housing protects the unit at primary impact points, supporting regular field use.
