Sends out 16 measuring lines, 8 vertical and 8 horizontal. Green laser beams ensure precise and clear leveling. A wall mount is included for attachment to the wall. Simply screw the metal plate to the chosen wall and then use the adjustable bracket with two strong magnets that ensure a secure connection with the previously screwed plate. This allows you to easily mount the level at any height on the wall. The level is made from durable material, and with an IP 54 protection factor, the device is waterproof, dustproof, and dirt-resistant. The self-leveling function can overcome small unevenness up to 3°; beyond 3°, the laser light blinks to remind you to place it on a level surface.
