Bosch Green-Beam Self-Leveling Cross-Line Laser GLL50-20G Blue 50ft

Description

Product Overview

The Bosch GLL50-20G Green‑Beam Self‑Leveling Cross‑Line Laser combines a high‑visibility green laser with intelligent pendulum technology. Housed in a rugged brushed‑plastic shell, the unit measures 4.1″ L × 2.5″ W and weighs just 12.3 oz, making it easy to carry on any jobsite. It projects intersecting horizontal and vertical lines that remain level within 5/16 in at 30 ft, and the green beam is up to four times brighter than standard red lasers, ensuring clear visibility even in bright daylight. Powered by two AA batteries (included) or an optional 3.7 V lithium‑ion pack, the laser offers up to 20 hours of continuous operation. An integrated magnetic mount and soft‑pouch complete the package for quick, secure placement.

Usage

Designed for professionals and serious DIY enthusiasts, this laser excels in framing, drywall installation, tile layout, and electrical conduit alignment. Its IP55 rating protects against rain and dust, so it can be used on construction sites, outdoor decks, and renovation projects without worry. The self‑leveling function automatically detects out‑of‑level conditions, flashing to alert the user before locking the pendulum for safe transport. Whether you are laying out a kitchen backsplash or aligning a wall stud grid, the compact size and magnetic mount let you position the laser on metal studs, concrete, or any ferrous surface.
