Easy-Laser® D90 BTA is compact and light, and suitable for most types of drive, such as V-belts, timing belts, flat belts and chain drives.

Easy-Laser® D90 is installed in a few seconds, and the laser line that is projected on the targets clearly shows how to adjust the machines. The tool has targets that can be read out "visually" and which give excellent degrees of accuracy that are sufficient for most users. If, in the future, you wish to have the option of digital readouts with the corresponding advantages, you can add a digital detector.
