Bosch GLL 12-22 G Green Cross Line Laser, 12m Range, IP55

GLL 12-22 G Professional Laser

The Bosch GLL 12-22 G provides high-visibility green laser lines for precise horizontal and vertical leveling on interior construction sites. This unit features a rugged housing designed to withstand daily trade use. It serves as a primary layout tool for installers requiring accurate references for alignment and squaring tasks.

Built for the Job

This leveling tool excels in interior finishing environments where ambient light often washes out standard red beams. The green diode technology offers up to four times better visibility to the human eye. Contractors use this device for installing suspended ceilings, aligning electrical sockets, and mounting cabinetry. The integrated T-mount system allows for rapid attachment to various surfaces without requiring additional bulky brackets. Its compact form factor ensures it fits into tight spaces between studs or inside utility closets. The internal pendulum system self-levels quickly, allowing the operator to start work within seconds of placement.

• Leveling electrical conduits and junction boxes during first-fix installations.

• Setting consistent heights for dado rails, tiling, and interior trim work.

• Transferring reference points from floors to ceilings for lighting layouts.
