Slip this laser into your pocket so it's on hand to align belts, pulleys, chain, and sprockets. Place the tool against the side of your pulley or sprocket and project the laser onto the included target to detect angular or offset misalignment. They mount magnetically, so you don’t need any fasteners to secure them. The surface of the laser is machined, so it sits flush against flat surfaces for easy and precise alignment. They’re powered by a disposable battery, so they’re portable.

Style B lasers have a threaded tip, so they’re compatible with converters that change the shape of the laser, so you can perform a variety of tasks with the same tool.
