This kit will securely hover your Aquaillumination modules smoothly above your aquarium, creating a sleek and innovative design. It is the counterpart to the EXT Rail. This kit includes 2 96" cables, 2 white metal canopies, 2 alligator clips, 2 machine screws, 2 cable grippers and 2 ceiling couplers. Easily adjust the height of your lights by pressing down on the top of the gripper in order to release pressure on the cable; followed by clipping off any excess wire. With simple installation, you will have your lights quickly. They are available in black and silver.
