Description

Master Full-Room Layouts with One Setup Using the Bosch 360-Degree Self-Leveling Cross-Line Laser

The Bosch GLL 2-20 S-RT Self-Leveling Laser Level is the ultimate efficiency tool for interior contractors, electricians, and finish carpenters. By projecting a continuous, bright 360° horizontal line, this laser eliminates the constant need to rotate or reset your tool, allowing multiple users to work off the same reference point across an entire room simultaneously. Whether you are installing wrap-around chair rails, aligning kitchen cabinets, or setting complex drop ceiling grids, this laser provides a level reference that is consistently accurate and highly visible up to a 65-foot diameter range.

Precision is made simple with the integrated Smart Pendulum System, which automatically self-levels and provides a clear alert if the tool is placed in an out-of-level condition. For versatile layout applications, the 120° vertical projection intersects the 360° horizontal line to create a perfect cross-line for plumb and square tasks. This reconditioned kit includes the BM3 Positioning Device, offering a flexible mounting solution for attachment to various surfaces or standard 1/4-20 tripod threads, ensuring you have the right setup for every unique jobsite challenge.

Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.

Key Features

  • Full Room Leveling: Projects a continuous 360° horizontal laser line, eliminating the need to reposition the tool for different sections of a room.
  • Smart Pendulum System: Automatically self-levels the laser lines and indicates out-of-level conditions up to ±4 degrees.
  • Cross-Line Functionality: Projects a 120° vertical line that intersects the horizontal line for precise plumb and alignment tasks.
  • Secure Transport Lock: The pendulum locks when switched off to protect the sensitive internal mechanism during transport and storage.
  • Versatile Selection Modes: Easily toggle between horizontal-only, vertical-only, or full cross-line modes to conserve battery life.
  • High Visibility Range: Delivers bright, clear red laser lines with a working diameter range of up to 65 feet.

Pro-Tip: To ensure the longest life for your laser level, always turn the power switch to the "OFF" position before moving the tool. This engages the pendulum lock, which prevents the sensitive internal self-leveling mechanism from vibrating or bouncing during transport, maintaining your tool's accuracy for years to come.
