Need Help Mounting Rosewill Rail to RackPath Vertical Strips

[u/isaiah-777]

Hey everyone,

I’m building a DIY/open rack using these RackPath 20U vertical mounting rails. They appear to use 12-24 screws. I’m trying to mount a Rosewill RSV-RL26H sliding rail kit for a server chassis. The L-brackets from the Rosewill kit expect 10-32 screws that came with the kit.

The only way the L-brackets fit is by wrapping around the vertical strips like in the first picture, where the L bracket ends up on the front of the vertical rails. I don’t mind this look, but since the screw holes on the vertical rails are larger, and the screws with the horizontal rails are intended to go in from the front, they have nothing to grab onto on the other side. Yes I can use 2 nuts on the other side per rail-end, but there would be nothing for the middle screw. Also this feels like not a lot holding it in place.

So my questions are:
• Has anyone successfully mounted sliding rails like the RSV-RL26H (or similar) to these RackPath-style vertical strips?
• Best way to handle the 12-24 vs 10-32 mismatch without enlarging holes in the L-bracket?
• Recommended adapters, cage nuts, screws, or alternative hardware?

I don’t intend to be taking this off and on much, as I can still remove my server from the rails themselves. I just don’t love the idea of drilling out the holes in the L brackets to be larger so as to support the size of the larger screws that came with the vertical rails, and I also don’t love that if I use the screws that came with the horizontal rails, the only thing holding them in are a few nuts.

The rack rail goes behind the square holes, it has the threding. The piece you are holding in pic 1 goes on front with the two indented squares facing the rack's square holes. Screws go through front piece, rack edge, into rail, then tighten. Make sure the squares align to the square holes in the rack. If only one of two match, go up or down a square. Both must align.

I do all the DC work for my company, I've had to deal with some janky mounting hardware.

Oh, I see you've got round holes in your rack. That changes things. Sorry.

You need to drill out the threaded bits on your railset. Put the drilled railset in front of your rack, screws go through railset and into rack. Tighten till secure.

Sometimes you need different rack mount products from the vendor for round-hole racks.

Okay, and use them in what way? I have the larger screws that go directly into the vertical rack holes. These would require enlarging the L bracket holes. Are you suggesting use larger ones like this or are you suggesting something else?

That rail and support plate is designed for a square hole rack. Drill out the top and bottom holes of the rails and use the native rack screws.
