Bosch GLL50-20GL Overview
The Bosch GLL50-20GL is a compact rechargeable green cross-line laser for everyday interior alignment and installation work. It projects one horizontal and one vertical green line, creating a simple cross reference without the size or complexity of a multi-plane professional laser.
65 ft Green Cross-Line Range
Bosch specifies a working range of up to 65 ft with ±1/4 in. accuracy at 30 ft. The bright green lines are designed for improved visibility indoors, while the Smart Pendulum System self-levels, signals an out-of-level condition and locks for transport.
Rechargeable or AA Power
The included 3.7V lithium-ion battery charges over USB-C and can be used while charging to reduce downtime. The tool can also operate on two AA batteries, giving installers a useful backup option if charging is not convenient.
Compact Jobsite Design
At under one pound, the GLL50-20GL is easy to carry and position in confined areas. The integrated magnetic mount and 1/4-20 thread provide flexible setup, while the IP55 housing helps protect against dust and water.
Who Is the GLL50-20GL Best For?
This model fits smaller flooring, tile, cabinetry and general interior jobs where portability and quick setup matter more than 360° room coverage.
