Bosch GLL 2-20 S-RT Reconditioned 360° Horizontal & Vertical Cross-Line Laser Level Kit

The Bosch GLL 2-20 S-RT self-leveling cross-line laser level projects a continuous 360-degree horizontal reference line and a 120-degree vertical beam across a 65-foot working diameter range with ±3/16-inch accuracy at 30 feet. Engineered for interior construction, cabinetry installation, suspended drop-ceiling grids, and electrical fixture alignment, this precision optical layout tool allows multiple trades to work simultaneously off a single room-wide datum line without rotating the housing. Equipped with the Bosch Smart Pendulum System that self-levels within ±4 degrees, a secure internal transport lock, and the versatile BM3 magnetic positioning mount, it provides finish carpenters, drywall contractors, and remodelers with rapid, reliable spatial squaring and plumb referencing across residential and commercial jobsites.

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

Best Used For:

  • Cabinetry and Countertop Installation: Projecting a continuous 360-degree level datum line around entire kitchens and utility rooms for uniform upper cabinet and base level mounting.
  • Acoustical Drop-Ceiling Grid Layout: Securing perimeter wall tracks and main runner tees rapidly at precise elevations using the included BM3 magnetic positioning clip.
  • Plumb and Level Partition Wall Framing: Intersecting 120-degree vertical and 360-degree horizontal beams to establish plumb stud lines, track squaring, and doorway alignments.

Key Performance & Safety Features

  • 360-Degree Horizontal Line Coverage: Delivers full-room level projection from a single setup position, eliminating rotational errors and repeat measurements.
  • Smart Pendulum Self-Leveling System: Automatically levels internal diode optics within ±4 degrees and visually alerts operators when placed out of level.
  • Secure Transport Mechanism: Automatically locks the optical pendulum in place when the power switch is turned off to safeguard sensitive calibration during transit.
  • Independent Line Mode Selection: Lets users toggle between horizontal-only, vertical-only, or simultaneous cross-line operation to optimize power consumption.
  • BM3 Magnetic Positioning Device: Attaches firmly to steel studs, metal ceiling grids, tripods via 1/4-20 threads, or sits freestanding with microfine height adjustment.
  • High-Visibility Red Diode Output: Generates crisp 635 nm laser lines delivering a working diameter range up to 65 feet for interior layout tasks.
