Bosch Self-Leveling Cross-Line Laser (Model GLL50-20)

The Bosch GLL50-20 Cross Line Laser delivers precision and versatility for all your leveling and alignment tasks. Its self-leveling Smart Pendulum System projects bright horizontal and vertical red lines up to 50 ft with ±5/16 in accuracy at 30 ft. Built to withstand tough jobsite conditions, it features an IP55-rated, full-rubber overmold housing and an integrated multipurpose mount (magnetic plus ¼″-20 thread) for flexible positioning.

Compact and lightweight, the GLL50-20 runs on two AA batteries (included) or Bosch’s optional 3.7 V Lithium-Ion 1.0 Ah battery. When switched off, the pendulum locks for safe transport, while the ergonomic design makes it easy to use and store.
