Slide the ReeFi Duo Extreme/Deluxe LED onto RMS rails.
3D Printed custom made RMS mount adaptor for ReeFi Duo Extreme/Deluxe LEDs.
When RMS arms are mounted flush against the tank, there is about 3.6degs droop when there’s weight on the arms. This is known issue with Ecotech’s RMS even with Radion LEDs. To correct for the droop, you can choose the 3.6degs angled RMS adaptor for ReeFi Duo Extreme/Deluxe LEDs.
In the photo below, the front ReeFi Duo Extreme is mounted with the Correction 3.6degs angled RMS mount adaptor where as the back unit is mounted with No correction angled.
