The Bosch BM1 positioning device is an incredibly versatile mounting solution for multiple line lasers. Its 1/4 - inch - 20 mounting thread enables seamless compatibility with various line lasers. This device offers multiple mounting options. It can attach magnetically to metal surfaces, stand on flat surfaces using retractable feet (acting like a mini tripod), or be mounted to drywall with screws, making it perfect for a wide range of interior applications. The fine - adjustment knob allows for super - precise alignment of the line laser. Its built - in mounting clip is a great asset for ceiling grid applications. What's included is just one positioning device, but it packs a punch with its features. It has a micro - fine height adjustment system for quick and secure setting of the working height. The multimounting system offers a variety of ways to attach, including strong magnets, 5/8 - inch - 11 and 1/4 - inch - 20 threads, slots for screws or nails, raceways, or optional straps. The clip attachment makes setup in ceiling grid applications a breeze. There are also threaded mounts (1/4 - inch x 20 and 5/8 - inch x 11) on the bottom for easy attachment to standard tripods or pole mounts. Additionally, it has three more mounting systems like strong magnets, slots for screws or nails, and raceways for optional straps. The height adjustment range is 2 - 1/2 inches.

Using the Bosch BM1 positioning device is easy. First, choose the right mounting option according to your needs. If you have a metal surface, use the magnetic attachment. For flat surfaces, extend the retractable feet to use it as a mini tripod. When mounting on drywall, use screws. To adjust the height, use the micro - fine height adjustment system. Turn the fine - adjustment knob for precise alignment of the line laser. For ceiling grid applications, use the built - in mounting clip for a quick setup. When using the threaded mounts on the bottom, make sure to securely attach it to a standard tripod or pole mount. As for maintenance, keep it clean from dust and debris. After use, store it in a dry place. If any part seems loose or damaged, check the mounting systems and make sure everything is tightened or replaced if necessary. Avoid exposing it to extreme temperatures or harsh chemicals to ensure its long - term performance.
