  • Quick Projector Disconnect/Reconnect: To quickly and easily remove the projector from the ceiling: loosen thumbnuts connecting the SLB bracket to the universal top. Remove projector and SLB from universal top. The universal top retains the registration adjustments. This feature makes projector servicing and maintenance quick and easy by eliminating the need for re-registration.

  • LSB100 Lateral Shift Accessory: Often times ceiling structures will not allow the projector to be mounted in exact alignment with the projection screen. The LSB100 Lateral Shift Accessory saves an abundance of time and hassles in trying to solve this common problem.

Also use the LSB100 to easily accommodate different lens placement when projectors are replaced in existing installations. Compatible with all RPA and UPC Series Mounts, and maintains quick disconnect feature. Includes All-Points™ Security System hardware.
