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

Description

Product Overview

The Bosch GLL50-20 is a self‑leveling cross‑line laser designed for professionals who need fast, reliable layout lines. Constructed from high‑impact plastic and rubber, the unit measures 4.1″ L × 2.5″ W and weighs just 0.77 lb, making it easy to transport and mount. It projects bright, thin lines that stay level within 5/16 in at 30 ft, and the smart pendulum system automatically self‑levels, blinking to indicate out‑of‑level conditions. The laser operates on two AA alkaline batteries (included) or an optional 3.7 V lithium‑ion pack for extended runtime. With an IP55 rating, it withstands rain, dust, and harsh job‑site environments.

Usage

Ideal for framing, drywall, tile work, and electrical installations, the GLL50-20 delivers consistent lines on walls, ceilings, and floors. Its compact size fits into tight spaces, and the integrated magnetic mount allows quick attachment to metal studs or joists. Whether you are working indoors on a renovation or outdoors on a construction site, the laser’s bright 630‑650 nm Class II beam remains visible in ambient light, ensuring accurate measurements in a variety of lighting conditions.
