Multi-Light RMS Radion Track 70.5" (Aquarium Length 68.5-78.5in) - EcoTech Marine

The Multi-Light RMS Track is the horizontal element of EcoTech Marine's Radion Mounting System, bridging the two vertical RMS Arms that clamp to the aquarium. On its own, the track does nothing — its value is as a precision rail that holds RMS Slides in any position across the span, letting you dial in the exact coverage pattern your system requires. For tanks in the 68.5–78.5 inch range, the 70.5" track (model XR703-0705) is the correct size selection.

The track accepts both XR15 and XR30 Radion fixtures simultaneously, so mixed lighting configurations are fully supported without adapters or workarounds. Slide mounts move freely along the rail until locked, giving you repeatable, consistent placement whether you're centering a single fixture or spacing three across a mixed-coral display.

Construction is anodized aluminum throughout — rigid enough to hold multiple fixtures without flex, light enough that the arm hardware is not overloaded. The profile also incorporates integrated cable management channels to route power and data lines cleanly along the mount rather than draping them down to the fixture.

The Multi-Light RMS is compatible with rimmed, rimless, and euro-braced aquariums, with the Arms handling the tank-edge interface. Fixtures hang approximately 7 inches (18 cm) above the waterline in standard configuration. To complete the mount, you will need to purchase the RMS Multi-Light Arms and the appropriate number of RMS Slides separately — the track alone is not a functional mounting solution.
