RMS Multi-Arm Radion Mounting System
Two anodised arms that turn a rimless tank into a multi-light rail mount. The RMS Multi-Arm kit supplies the pair of vertical uprights that anchor EcoTech's modular Multi-Light RMS system to a tank rim or glass edge up to 35 mm (1-3/8") thick. It's the structural half of a three-part system — an RMS track and an RMS slide for each fixture complete the setup — built for reefers running two or more Radion XR15 or XR30 lights over one tank.
Key features
- Anodised aluminium construction — rigid enough to carry a multi-light rail without sagging at the ends.
- Clamps up to 35 mm of glass or rim — works on rimmed, rimless and eurobraced tanks.
- Built-in cable management — routes Radion cabling down the arm instead of trailing across the water's surface.
- Shares one rail with XR15 and XR30 — mix fixture sizes on the same track.
- Mounts the light about 180 mm (7") above the waterline once paired with a slide, per EcoTech's own multi-light diagrams.

What's in the box, and what you'll still need
Suitable for, and not suitable for
Suitable for: tanks running two or more Radion XR15 or XR30 fixtures on a shared rail, and single-light owners upgrading to a wider multi-light spread.
Not suitable for: a single fixture on its own — buy the RMS XR15 tank mount or RMS XR30 tank mount instead — or any tank rim or glass thicker than 35 mm.
Goes well with
- Radion Multi-Light RMS Rail — the horizontal track these arms clamp to.
- Radion RMS G6/G5 Slide — one per fixture, lets each light slide along the rail.
- Radion XR30 PRO LED — EcoTech's current flagship fixture for this rail.

Common questions
Does this include the track and slides?
No. This kit is the arm pair only. You need an RMS track sized to your tank and an RMS slide for each Radion fixture to complete the system.
Will this fit a rimless tank?
Yes. The clamp works on rimmed, rimless and eurobraced tanks up to 35 mm of glass or rim thickness.
Can I mix XR15 and XR30 fixtures on the same rail?
Yes. The Multi-Light RMS system is designed to carry XR15 and XR30 fixtures on the same track.
How far above the tank does the light sit?
Once paired with a slide, the fixture sits roughly 180 mm (7") above the waterline, per EcoTech's own mounting diagrams.
