BOSCHSelf Leveling Cross Line Laser GLL 30

Q: Can this be used to level a subfloor?

Thank you for your question and interest with our GLL 3 Self-Leveling Cross-Line Laser. This is meant for aligning and not leveling. We highly suggest our GSL 2 Surface Laser designed for determining flatness and level of flooring. https://www.boschtools.com/us/en/boschtools-ocs/line-lasers-gsl-2-37290-p/ For further assistance you may visit our website: https://www.boschtools.com/us/en/ or you may contact us on 1-877-BOSCH99 (1-877-267-2499).

Q: Does the laser level need to be at the same level as the line it is projecting, or can I project a line 8 feet high on a vertical 4x4 post?

The GLL 30 Line Laser can be positioned or mount using a positioning device even higher as long as it is level. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

Q: Can I use this level to determin if the floor in a room has settled on one side compared to the other?

Thank you for your question. The GLL 30 Self Leveling Cross Line Laser does the job for leveling and other alignment tasks, like cabinets. For your application, I recommend using a leveling surface laser level, like the GSL 2. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

Q: Can this be “locked” in and used at a 2 degree angle (1/4” per foot slope for plumbing) or will it only work at angles 4 degrees and above ?

No it cannot. The product description is innaccurate. The GLL 50 has a lock/unlock switch for manual mode, this (GLL 30) does not.
