Bosch Self-Leveling Cross-Line Laser GLL50-20

The Bosch GLL50-20 is a compact, entry-level layout tool designed to project highly visible horizontal (level) and vertical (plumb) lines simultaneously or independently for precise alignment tasks. It is widely used by DIY homeowners and professionals alike for projects such as hanging shelving, leveling pictures, or installing cabinetry. • Range & Accuracy: Projects a bright red laser beam with a 50 ft. working range and an accuracy profile of ±5/16-in at 30 ft. • Smart Pendulum System: Automatically self-levels up to ±3.5 degrees and flashes a blinking line indicator if the unit is placed out of its level orientation. The pendulum locks securely when the power switch is turned off for protected transportation. • Dual-Power Flexibility: Operates out of the box using two standard AA alkaline batteries (included), but is also compatible with a Bosch 3.7V Lithium-Ion rechargeable battery pack (sold separately) to reduce project downtime. • Jobsite Durability: Features a full rubber overmold "roll cage" housing designed to protect vital impact points from unexpected drops, carrying a rugged IP55 dust and water resistance rating. • Mounting Options: Includes an integrated multi-purpose magnetic mount to snap onto metallic frames or walls, alongside a standard 1/4"-20 threaded mount for attachment to common tripods.
