Radion 60 inch light rail question

[Jimbo]

I’m thinking of switching my light set up you see here with a 60” light rail due to sagging from the AI Blades as you can see here.
Can I use the 2 of the RMS mounts I have to hold the rail or is something else needed?

Any other suggestion to fix the problem? I’m using 2 3d printed holders right now that are attached to two of the xr15’s to hold the blades but it pulls the Radions down a little bit.

I use the RMS mounts with the rail. I have 4 XR30’s on a 6’ span with no sag.

Thank you

What length rail for a 5 foot tank? Can I get away with the 50.5” ?
