The GLL 2-20 S 360° horizontal cross-line laser delivers everyday convenience and precision. The 360° line coverage gives the user the ability to line up an entire room from 1 setup point. It also features a vertical projection of 120° for cross-line applications. The bright 360° horizontal line allows the user to project a laser reference line around the room with accuracy to quickly establish level, enabling users to work in different parts of a room simultaneously. The GLL 2-20 S range is 65 ft. Dia with accuracy of ± 3/16 in. at 30 ft. Smart Makes Things Easier Combined with the Smart Pendulum System the GLL 2-20 S offers self-leveling, 1-time setup and an out-of-level warning indicator.

I should have purchased one of these years ago…speed and efficiency are what makes you money on a job and the Bosch GL-2-20 helps with that goal along with the accuracy from Bosch which one expects!

Works well. I needed to use it outdoors and found that i could see the laser better over 65 feet at night/dusk. I have not totally figured all of the uses. Luckily for me and because I needed to use it near the ground, its height was just right. Any taller and it would have not worked for me. I think in the long run I can find other helpful uses.

I used this to set the patio stones on an above ground pool installation and it worked great.

Perfect tool can be used everywhere on anything, reliable and accurate.

the mounting screw (1/4-20 thread) is too small. I made my own adapter to fit my tripod which is 5/6-11 treads. using the tripod means that you can crank it up or down to re “zero” a line over the wall if you have to move it and reset. it is a good unit and the level function is great.

In regards to suspended ceiling installation. The clap as shown in the manual does “NOT” clamp on ceiling grid as shown, It must be hung on the wall or mounted onto a tripod. Tripod cost extra.

This laser isn’t bad. I would say it feels a little cheaper than the Bosch Lasers I have purchased in the past.Comes with everything you need to use this right out of the box.Off switch actually locks the internal mechanism so it’s not bouncing around when you driving down the road.Auto leveling.You can select horizontal 360 line, vertical line, or both. The vertical line is much more prominent that the horizontal 360 deg line.There are two magnets on the attached stand that are neodymium type and are pretty strong. I would say this is a really good tool for the DIY person that may be putting shelves in the garage, or cabinets in the kitchen. For someone doing commercial work this might not be quite enough.Bosch lasers are my go to for lasers, They are good, affordable, and just work. My oldest Bosch laser is probably 5 years old and has been dropped, kicked, thrown, and beat to death in my toolbox. They just continue to work.

I like it very much. It is a great help when you work alone. I would recommend the laser.

This is a nice level that will project a horizontal level line all the way around the room and also can project a vertical line in front. You can change the mode to have just the horizontal line, just the vertical line or both. Runs on 4 AA batteries which are included. Lines are bright and easy to see indoors. Can project up to 65 ft, the self-levelling happens quickly. You just need to get it within 4 degrees of level first. On/off switch turns off the unit and locks the self-leveling pendulum swing.There’s a lock button you can use if you want to project lines that aren’t leel. Unlick other self-leveling laser levels I’ve used this lock button doesn’t actually lock the pendulum. It just keeps the laser from turning off when it’s past 4 degrees. That means if for some reason you need to project a line that’s 0 to 4 degrees off level you can’t really do it with this. Probably not something most people would really need to do with this though.The bracket that comes with it is pretty neat but doesn’t have a wide range of motion. It’s basically just an L-bracket with a couple of magnets. This would be a good bracket to use in a commercial space with metal studs. You can mount the magnetic bracket to a steel stud and project the lines for doing other work such as installing a drop ceiling grid, marking heights of outlets, switches and things like that.Comes with a case that can be hooked on your belt easily with a velcro belt loop. Nice thing about the case is it not only fits the level but also the bracket. Another Bosch laser level I have only holds the level, not the bracket.If you plan to use this laser level (or most any other laser level) a lot I would recommend getting a good, sturdy, heavy photographic tripod. That will give you greater flexibility and control over the placement of your lines. There’s a standard 1/4-20 threaded insert in the bottom of the level.Level appears to be well made and constructed of durable plastic.

This is a device I wished I started with when developing my basement. I bought it when I installed a suspended ceiling and what a difference it made.I suggest to register your tool as I did not and will in the future. I had a mishap with the level and ended damaging the top laser protector. I called Bosch and was in luck I only had it for a short period and was directed to send in for a fix. I did so and in a short time later I ended up with a new unit. I suppose it could not be repaired. With great thanks to Bosch for taking care of every thing. I am one happy customer

Easy to use. Not for full sun use. Using a tripod helps a lot.

If you’re accustomed to using tape measures, string levels, long contractor levels, plumb bobs and inexpensive laser levels to tackle tile wall layouts, suspended ceiling grid layouts, window/door framing and so forth, this tool will probably beat them all for ease of use and accuracy, provided you’re not working in brightly lit conditions. The inexpensive levels I have used were a waste of money, projecting a beam that was seldom useful. I really wish I had this product in hand when I was tackling those projects.This product gives the feeling of a well-built tool, beginning with the solid casing material. Operation of the laser’s standard features is fairly intuitive, which is very helpful because who wants to search for the instructions in the middle of a job? The self-balancing feature is a blessing when working in older houses when nothing you rest the laser on is likely to be level.The bright laser is easily read indoors in areas of indirect sunlight or dimness. Under those conditions, I was able to see the line projections from 35’ in a dimly lit setting, but was limited to 10’ to 15’ in a big room with large patio doors (see pictures). Outdoor visibility is nonexistent. The laser came with a single attachment – a positioning device that screws into the bottom of the laser, that allows (1) horizontal surface mounting or (2) wall mounting of the laser with screws or (with an internal magnet) to a metal stud or surface. The laser can also be affixed to a tripod using the ¼-20 mounting thread on the bottom of the device. (see pictures) The user manual indicates that an additional mounting device is also available for separate purchase that will accommodate mounting the laser to ceiling grids, etc. The laser uses 4 alkaline AA batteries that are supplied with the kit, and easily installed without tools. I’ve had the tool for just a short time, so I can’t say how long the batteries will last. Unlike some other Bosch laser models, this one does not have an automatic shutoff feature, so if you forget to turn off the laser, you could be out of luck next time you go to use it. Unfortunately, this sort of thing has happened to me more than I care to admit.Operation of the laser itself is straightforward, with a “mode” button that allows instant switching between projecting a horizontal line, a vertical laser line or a cross-point (both lines intersecting) each time it is pressed. The laser will display a line that completely wraps around the room – great for positioning chair molding, cabinets or hanging patterned wallpaper, tile, etc on adjacent or opposing walls.There may be times you want a straight line, but not a level one and in those instances, the auto-level feature is easily deactivated with the push of a button. The tool comes with a brief instruction manual that includes a few graphic illustrations that show how the tool can be used for a wide variety of measurement applications. However, there is no indication that there is any way to mechanically confirm the accuracy of the level and plumb lines, or to recalibrate them. Finally, it comes with a small nicely fabricated tool pouch, with Velcro closure to protect the laser in storage. Although this is a quality precision tool, well-designed for the serious DIY’er and professional tradesman, the limited visibility of the laser lines in brightly lit areas could pose a problem for some applications, and might require a trial usage to determine if this is the right tool for your situation.

The Bosch Company makes quality tools at affordable prices. This rotating laser is very accurate horizontal and vertical. It is super easy to set up and operate. This laser makes lettering, stenciling, and much more easier and straighter. How do you get perfectly straight lines on uneven surfaces? You get this 360 degree laser. It can even help line things up in multiple rooms when set up properly.

We needed a line laser for our home renovation project. We purchased it for the new kitchen cabinets we’ll soon be installing but have used this on several other projects as the entire laser line on the floor or wall makes it considerably easier. It has a built-in level and will mount on a standard tripod and you can switch from horizontal to verticle or both. I would highly recommend this device! Way easier than a spot laser level for what we needed and we already own spot levels.

I got the cross line laser level because I got tired of holding the level on one hand and marking with the other. I have also used a suction style laser level, but it didn’t work well on rough surfaces and sometimes moved or the laser would not project well on the wall…enter the cross line level and after its first use you will find it is money well spent. If you are installing shelves or frames on several walls, just place it in the center of the room, turn it on and you have perfect level bright lines all around. Right next to where they sell the level, they also have the tripods…those come in very handy, and if doing more than one job I also recommend you get it. Bosch makes a quality product that performs flawlessly.

This is another fine product that I purchased from HD that I have no idea how to use and haven’t seen since I bought it several weeks ago but I would highly recommend it because I like the way the name “Bosch” just rolls off the tongue. Dewalt sounds like a brick hitting a wall, Bosch sounds like a wave hitting the beach. Boschhhhhhh.
