1 out of 5 eggsI really hoped these would work for me

Pros: None for my situation.

Cons: I purchased these for a NORCO RPC-340 case (which I gave 4 eggs!), first NORCO case I ever bought. Found out the case only has 3 holes on the sides and would not line up with universal rails that I had laying around. So I checked on their site and ordered these from here.

I put them on and pushed the case into the rack, was a little tight at first, but didn't think anything of it being the first time.

But then I pulled it out, well.... attempted to at least.
It was stuck.

I thought the locking mechanism was tight from being new or stuck.

After much and much more struggle, I had to wiggle it side to side to get it out of the rack.

The side of the case has slight rubbing marks and the top rear of the case ACTUALLY BOWED IN!


Because the front and rear L-mounts that connect the the rack actually arch toward the case, you can't really see it in the picture here. Before I put it together I assumed that they would clear the case since these are made by the same company and they state they work.

But no, I think it is just a horrible design.

After inspecting and attempting a second time just for giggles and failing in the same manner. I took the rails off, drilled 3 new holes to allow me to use 4 screws on each side of the universal rails I had. (yeah 1 more than NORCO gave me).

Server now slides in and out of the rack perfectly and I have two extra metal rails to beat zombies over the head with if it ever comes down to it.

Other Thoughts: I have tons of other server cases, switches, routers, UPSes, shelves, drawers, KVMs, etc in these same racks. So maybe my racks are compatible with NORCO rails or maybe the rails are just badly designed with no flexibility in use, even with their own products.

I can't even remember the last time I gave less than a 3 egg review, this alone saddens me.

5 out of 5 eggsGreat

Pros: -Works in 4-post rack.

Cons: -Not confusing but difficult. (Explained below).

Other Thoughts: I want to expand on the con I listed. I used these rails on the Norco RPC-170. The top won't neatly fit on with the rails on. You have to apply significant pressure to allow the top of the case close while the rails are attached. While screwing the rails on with the case closed, you have to press hard towards the top of the case for the screw holes to align correctly. The holes for the screws are JUSSSSTTTT off enough where it causes a bit of trouble. So if you ever want to take it apart, you might have to take the rails off as well. Possibly a defect, design flaw, or something but the rails are on the correct way but cause a bit of problem.

It did fit in my 4-post Tripp Lite 25U rack neatly and easily though.

I would probably buy these again.

4 out of 5 eggsPretty good, rarely won't fit some racks

Pros: Well constructed and the action on the slide is very nice. Lines up with the mounting holes and feature on the Norco case I have (RPC-430). Not expensive.

Cons: Does not fit with a rack that has U-shaped posts. My rack has U-shaped posts with holes along the front but also holes that are behind and perpendicular to the front face. Paired up with my RPC-430, these rails require some mechanical clearance behind the front face of the post so that they may recess to allow for enough clearance for the case to fit between the two front posts. See this picture for what might work (left) and what doesn't (right). I ended up cutting a notch out of my rack for them to fit.

4 out of 5 eggsNice rails for Norco

Pros: Works well on the norco 230 and 430 case. It is different than the pictures, but it works great for all my cases. The ends are pretty easy to setup. Don't know how other cases work, but it works great in norco cases and norco racks.

Cons: There is no instructions except for a picture online. On the other hands, rails are too complicated. Knocked it one beg for lack of documentation/instructions.

2 out of 5 eggsSquare compat only?

Pros: Ball bearings will likely support the rated load, well machined so as to not cut off my fingers while handling. Good turnaround on support request from Norco email.

Cons: Does not fit my threaded rack. I have bought this "exact" item twice before in the past and it had L brackets for "inside mounting" to the side holes, and it worked well.

Well, now they ship without the L brackets, they mount to the front lip of the rack instead of the side lip, and they simply don't come close to fitting threaded systems. Consider this for square hole racks only.

Other Thoughts: Support request to Norco was answered almost immediately with pictures of the rails mounted to a square hole rack, as if to prove to me that they are not totally worthless. He confirmed "we redesigned it" and this is not simply a matter of missing parts in my shipment.

When you redesign a product in a way that it affects compatibility, you should change the model number, so people don't reorder it expecting the same thing. shame shame.

1 out of 5 eggsPoor quality garbage from Norco

Pros: The ball bearings allow the case to slide in and out well, once you get it on the rails...

Cons: The two pieces of rail that attach to the case are identical instead of mirrored. They did not come with instructions on how or where to mount them, since they are made to work with different cases, and the cases different rails. The rails do not extend out far enough for you to remove the lid, or to be able to reach all components in the case.

Other Thoughts: I will steer clear of Norco products in the future, the two products I have purchased of theirs are both worthless.

2 out of 5 eggsLimited mounting options

Pros: I got it to work. Norco seems to have good customer service.

Cons: Not at all what is pictured. The larger l brackets have only 3 pre-threaded holes (2 used) and uses a sandwiching method (bracket->rail->metal plate) to mount to the posts. It isn't possible to use cagenuts or even the screws for a pre-threaded rack. Does not include the smaller L-mounts pictured for inside-mounting in a server cabinet. Product that comes from newegg will not work with RPC-4220, but you can call Norco to get a replacement (I have an extra set of these now; they didn't want them back)

Other Thoughts: I had to drill out holes and use the small L-mounts from another rail kit to get it to mound inside my Compaq 9000 series server cabinet. Using with RPC-4220 rev. 2 (it has a tab towards the front to attach rails). It is entirely possible that I don't know what I'm doing since this is my first rack-mount server, but my overall technical knowledge is high. My roommate bought rails for a different case that were much easier to use. Newegg, please open up a box and take new pictures!

1 out of 5 eggsDon't Buy

Pros: Okay for some server chassis.

Cons: Picture is not what you get. Be careful. I though the metal arms had many hole mounts but didn't.

Other Thoughts: I have a ARK 4U-500-CA Black 4U Rackmount Case and the holes don't line up.

Manufacturer Response:

Dear Valued Customer,

Both RL-26 and RL-20 are ball bearing rails, support all Norco rackmount cases.

4 out of 5 eggsNew mounting system?

Pros: Works well with 430mm chassis, slides smoothly. New system does not require metal grinding.

Cons: Still hard to install.

Other Thoughts: Just got both a RL-26 and RL-20. RL-26 is still using the mounting system as pictured. RL-20 appears to have received an update. On my rack I've had to mount these on inside of the rails. The old system requires that I grind 2mm off each bracket to fit my cabinet rails. Needless to say it's a PITA.

The RL-20 new system requires that you do inside mounting unless you're handy with power tools. However it comes with brackets that help you line up with the square holes and mounts flush. Much improved over the old system.
