Product Overview


The Bosch GLL 55 Professional Self-Leveling Cross-Line Laser projects vertical, horizontal and cross lines, independently or together. It features VisiMax technology, for outstanding line visibility in standard working conditions. The locking Smart Pendulum System provides accuracy, reliability and durability. The tool is easy to use and provides a variety of essential level and alignment applications. The unit is constructed to withstand harsh jobsite conditions. The set includes a magnetic L mount that attaches to steel studs, and it is equipped with free-standing mode functionality. The included hard carrying case provides for more secure laser transport.
VisiMax for outstanding visibility - The GLL 55 Cross-Line Laser features the Bosch-exclusive VisiMax technology, which delivers maximum beam brightness in most jobsite conditions. It provides highly visible lines while protecting the laser diodes from overheating. VisiMax constantly monitors the laser's temperature so the diodes are always driven to deliver the best line visibility while preserving the life of the tool.
Layout efficiency - This professional cross-line laser includes vertical, horizontal and cross-line modes, which can project two lines independently or together. The GLL 55 has a manual mode that allows the user to lock the cross-line, to use the tool at any angle. The laser's lines are highly visible up to 50 Ft. and offer accuracy of ±1/8 In. at 33 Ft. The tool provides a long vertical laser line that extends line visibility to a nearly 360-Degree vertical plane when placed next to a wall.

Very nice line laser
There are a couple of nice features on this laser that I hadn't previously seen that are nice.
1. It has a lock on the line laser so you don't need to have it in a horizontal or vertical position for when you need to project an angle.
2. It also locks the pendulum mounted auto leveling laser so it is less susceptible to damage when moving it around.
3. It has two different mount threading’s on the bottom so it can work with the bigger 5/8’s rotary style tripods as well as smaller ¼ camera style ones. I had to buy a converter for my other laser to work on my Bosch tripod.
Another nice touch on this is it has a place for a spare set of batteries. It's also smaller than some of the competitors if that is important to you. I checked the line width against another brand and they were equally accurate (or inaccurate if you are a pessimist) with the same width. Overall it’s a great value relative to the other models on the market given it is $20+ less than the most popular competitor.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
