As with the ReefLED 160S Universal Mount Arm, the new ReefLED 90 version attaches firmly onto the rear wall of the tank and can be rotated to the upright position during reef-scaping or other tank maintenance.
Set at the correct height above the aquarium, the mount arm can be adjusted to suit tank widths of 18¼”–27½” and with glass thickness of 5/16”- 3/4”.
