Dominate Outdoor Grading and Layout Tasks with High-Visibility Green-Beam Precision

The Bosch GRL18V-31K 18V Green-Beam Horizontal Rotary Laser Kit is a comprehensive, ultra-precise site leveling solution built to withstand the harshest commercial contracting environments. Featuring an advanced green-beam laser diode that projects a line up to four times brighter than standard red beams, this high-performance transit level provides exceptional visibility across long distances, even under direct sunlight. Engineered specifically for massive outdoor grading, concrete formwork alignment, and excavation setups, this system features a streamlined, one-button user interface that eliminates complex menu tracking. Turn the tool on, and its smart internal systems handle the rest, enabling seamless automatic self-leveling so your crew can get to work immediately.

Engineered for maximum versatility on unpredictable terrain, this structural leveling tool features a wide ±15% self-leveling range that ensures rapid, error-free setup on uneven ground. Its heavy-duty composite framework is IP66-rated to be completely dust-tight and resistant to high-pressure water jets, and it has been officially drop-tested to survive a 5-foot tripod tip-over shock. To prevent costly downtime on remote jobs, the laser boasts a flexible dual-source power system, allowing it to run continuously on the included universal AMPShare 18V Lithium-Ion battery pack or standard C alkaline batteries using the provided adapter sleeve. Complete with a heavy-duty tripod, a telescoping grade rod, and a robust laser receiver, this kit provides a 1,000-foot working range with an accuracy of up to ±1/16-inch at 100 feet.

Key Features

  • Ultra-Bright Green Laser Diode: Delivers exceptional visibility that is up to 4X brighter than classic red lasers, optimizing performance for long-range outdoor layouts.
  • Rapid One-Button Interface: Simplified singular button design streamlines setup and operation while full automatic self-leveling eliminates manual calibration errors.
  • Dual Power Flexibility Architecture: Operates seamlessly using the included 18V 4.0Ah battery pack or conventional C alkaline cells for flexible power management.
  • IP66 Environmental Rating: Heavy-duty dust-tight construction shields delicate internal optics from harsh windborne site dust and powerful rain or water splashes.
  • Massive 1,000-Foot Operational Range: Provides dead-on reliability across vast distances with a tight structural accuracy of up to ±1/16 in. at 100 ft.
  • AMPShare Battery Compatibility: Part of a cross-brand cordless ecosystem, the included battery works across an expansive array of professional power tools.

Pro-Tip: Before beginning a long grading run, clear any direct optical obstructions within a 5-foot radius of the tripod stand. Because green-beam lasers operate with incredible light intensity, keeping the immediate path free of thick dust blankets or hanging foliage stops the light plane from scattering prematurely, preserving maximum signal clarity across your full 1,000-foot work site perimeter.

Great home office dividers!
Size: 3-Panel
Needed something to create a home office that would stand on an uneven basement floor. These are the perfect solution! No prying eyes and only took me an hour to put up both sets by myself, pretty easy. They are completely opaque.

Fine Simple Product, Works as Advertised
Size: 3-Panel
Performs as advertised, a simple upright divider. I use it to mark my "office" space when working from home. Assembly was straightforward and well documented. One person can do it, but a second person can be helpful when sliding the fabric divider pieces onto their poles. Part quality is fine for the price point. The only mild annoyance is that the upright poles can start getting loose from the metal feet, and need to be retightened occasionally (Allen wrench is included, keep it handy for retightening). It's fairly lightweight and easy to reposition, but the feet are heavy enough to keep it steady once placed. All in all, a good product. I was pleased enough to buy a second one when my son wanted something to block sunlight from behind his computer desk.

Wobbly and Poor Design
Size: 1-Panel
Update: nope! Not worth the money. My cat simply brushed against the divider, and it fell, knocking breakable things over. Not safe! It serves it's purpose, but...the screws were basically glued to the packaging. It took me longer to get the screws out of the packaging than it did to put it together. The assembly was easy. I am not mechanically inclined by any means, but the instructions, despite being very hard to read (I have over 40 eyes), were pretty simple. Structurally, it is very wobbly. I think they should have designed it with a middle rod to keep it more stable. I find that the attachments to the rods are wobbly and should have been screwed rather than popped into an attachment hole without reinforcement. That would have also made the room divider more stable. I have cats, but the material is easy to clean. I took a damp cloth to it, and it came right off. As far as see-through...I think it does a great job of masking theO other side of the room.. I just wish it was a little longer and closer to the floor stand. I like that it came with extra parts. It's just a very cheaply made item, and I don't think the price for the item reflects how cheaply it is made, how wobbly and unstable it is, or the poor design.
