Radion RMS Track 50.5" — Multi-Light Aluminum Rail for 48-58" Aquariums - EcoTech Marine

The EcoTech Marine Radion RMS Track 50.5 inches is the anodized aluminum horizontal rail that spans your aquarium between the two RMS arms (Arm Pair). This is part "B" of the RMS Multi-Light modular system — the rail onto which the Slide mounts slide to precisely position your Radion lights. This 50.5-inch (128 cm) rail is suitable for aquariums from 48.5 to 58.5 inches in length — ideal for 5-foot aquariums and large reef systems.

Rail Length Guide — Which Rail for Your Aquarium?

The RMS arms extend 3 to 4 inches beyond each side of the aquarium. The rail should be chosen based on the total length of your aquarium. Here is the matching guide:

• 20.5 in (52 cm) Rail: Aquariums from 18.5 to 28.5 in
• 30.5 in (77 cm) Rail: Aquariums from 28.5 to 38.5 in
• 40.5 in (103 cm) Rail: Aquariums from 38.5 to 48.5 in
• 50.5 in (128 cm) Rail: Aquariums from 48.5 to 58.5 in — this product
• 60.5 in (154 cm) Rail: Aquariums from 58.5 to 68.5 in
• 70.5 in (179 cm) Rail: Aquariums from 68.5 to 78.5 in

The rail is adjustable front to back on the arms. Even if your aquarium is not a standard length, choose the closest rail — the system adjusts.

Typical Configuration for a 5-foot Aquarium

A 5-foot reef aquarium typically uses two or three Radion XR30s for optimal PAR coverage across the entire surface. The complete setup requires: 1 pair of RMS arms (Arm Pair), 1 RMS 50.5-inch rail (this product), and 2-3 XR30 Slides depending on the number of lights. You can also combine XR30s and XR15s on the same rail to adjust coverage according to your coral placement.

Parts Required for a Complete Multi-Light System

• A — RMS Arms (Arm Pair): Pair of vertical supports on the edges of the aquarium — sold separately
• B — RMS Rail (this product): Horizontal bar between the arms
• C — RMS Slides: One sliding mount per Radion light (XR15 or XR30) — sold separately

Alternatively: the rail can also be suspended from the ceiling with the RMS Hanging Kit (XR717) instead of the arms.

Frequently Asked Questions

Is the 50.5-inch rail suitable for a Red Sea Reefer 525 or a 60-inch aquarium?

For an exactly 60-inch aquarium, the 50.5-inch rail will be a bit short — it covers up to 58.5 inches. The 60.5-inch rail would be a better choice. The 50.5-inch rail is perfect for aquariums from 48.5 to 58.5 inches, such as Red Sea Reefer 450s or standard 150-gallon aquariums.

How many Radion XR30s can I mount on a 50.5-inch rail?

Two or three Radion XR30s fit comfortably on a 50.5-inch rail. Two XR30s provide full coverage for a mixed reef. Three XR30s provide very high PAR for the most demanding SPS-dominated aquariums.

Is the RMS rail the same for XR15 and XR30?

Yes. The rail is universal — it accepts both XR15 and XR30 Slides on the same rail. The difference is only in the Slide model used. You can even mix XR15 and XR30s on a single rail.
