Slip this laser into your pocket so it's on hand to align belts, pulleys, chain, and sprockets. Economical and simple to use, just press the tool against the side of your pulley or sprocket and project the laser along your belt or chain to the aluminum target (included) to see any misalignment. It has a machined aluminum surface that is adjusted parallel to the contact surface for precise alignment.

Style B lasers have a threaded tip, so they’re compatible with converters.
