Red Sea ReefLED RL50 Mounting Arm

ReefLED™ mounting arms are universal mounts that securely attach onto the rear wall of the aquarium and can be rotated (side to side), allowing greater access to the aquarium for reefscaping or tank maintenance. The RL50 is suited for aquariums with widths from 36-51cm / 14 to 20" and a glass thickness of 8-15mm / 5/16 to 3/8".
