Build a one-of-a-kind mounting and hanging system for your Hydra lights. Mount multiple lights across your aquarium with the 25.5” rail to illuminate your aquatic life. Sleek design hides away cables for a clean look. Rail is compatible with the Hydra TwentySix, FiftyTwo, and HD LEDs. Allow for full functionality with the slide and swivel feature. HMS brackets are not included with the HMS Rail.
