The BM3 Positioning Device offers workers the versatility needed for multiple leveling and alignment applications, while eliminating the need to change mounts. The BM3 can be magnetically attached to metal surfaces, set on the floor with retractable feet, mounted to drywall or wood with screws, or attached with a spring clip used for quick setup in ceiling grid applications. It also features a fine adjustment knob for quicker and more accurate tuning of horizontal leveling. The tool can be used with multiple lasers with ¼-inch, 20 thread (1-pound maximum weight).
