The Erbessd Reliability EI-Pulley Ace alignment laser features retro-reflective alignment targets that work indoors or outdoors using enhanced reflective technology. The laser lines can be seen better in direct sunlight and adjustments are easier to make.

The EI-Pulley Ace projects a plane of laser light parallel with the faces of drive and driven sheaves. Adjustable targets attach to sheaves, intersect the laser beam and visually show any misalignment. The retro-reflective film on the center line of the target reflects the laser beam and glows for enhanced visibility and accuracy.
