RackSolutions 1U Cable Management Arm

I use this with my Silverstone RSV-L4500U and RSV-L4000U cases. It works great for keeping all the cables out of the way and tidy. Now I can slide the cases out every few years for dusting without anything on the backside getting caught or snagged.

Finally decided to go with a full 4-post rack in my closet due to explosive growth in storage needs over the last two years.Decided to buy a pair of 4U chassis, got their matching rails, and because there is 0 access to the BACK side of the rack, I REALLY needed cable management arms. Low and behold, there's not really that many arms out there that are truly universal. Actually, to be honest, this is the ONLY 1U arm I could find that is actually universal. Took a little finagling to get installed, had to use thinner bolts to mount it, make sure you use something a little thinner... Not sure if I had used 10-32 or 12-24, I know M6 (my go-to) wouldn't fit the holes to mount it to the rack.I saw an earlier review that mentioned they had to modify their rail, and attach the arm to the rail, there is no need to do this. Though, mounting with 1U server isn't ideal, they do include a plastic strap that you can use instead of the adhesive bracket, it would idealy attach to the case somewhere, either with zip-ties, or by using the cables to hold the arm in place. Certainly not ideal, but better than modifying your rail.Best case scenario? Works perfect for 2U or larger chassis! Bought one to test out, worked GREAT, bought another one today, and going to buy 4 or 5 more over the next few months as I get more servers mounted on rails.Caution: You WILL have to adjust it a good bit to fit your rack and chassis. Plan on sliding your case in and out a few times with out cables to make sure its extending enough for the case to hit its stops.Pros:Came with multiple attachment methodsArms can be detached at each joint should it ever actually be needed (HUGE plus in my situation!)Has small slots cut out along the length, so you can attach velcro to keep your cables in the arm.Sturdy enough to support its own weight, 1 power, 1 fiber, 2 Cat6 STP cables with a little more room.Highly adjustable length wise at the middle pivot points.Cons:Price - a bit on the expensive side for what it is.Cotter Pins hold the pins down, just an annoyance for me.

This arm really is a *universal* cable management arm. It comes with three ways to attach the server side: A sticky sidemount flap (shown), a custom mount I didn't have hardware for, and a lanyard. It takes on 1U of space. It is adjustable in length to a bunch of sensible sizes.I have 4 on the servers in this rack. This is in operation and each arm has power 16ga, Cat6/Cat6 plenum,HDMI, and USB. This isn't a ton but I think even with dual power and dual network these arms would still work.In the images I used the include cable tie cut that I manually cut to length, they fit snuggly into the slots on the arms and I don't think they will fall out even when open. These came with a smattering of bolts and cage nuts, RackSolutions makes great hardware and include 3 sizes M5, Something SAE/imperial and M6. We standardized on M6 for our racks so that worked for us (but the SAE has the nicer bolts.Each arm has two adjustment points to make it longer or shorter. We didn't need any odd tools to do the adjustment. Our tool kit has common tools pliers, screwdrivers, or alan keys, it was one of those we used to adjust it.For a DIY server deployment these are amazing. I would not recommend for people wanting a turnkey solution, but I would recommend for people solving problems and seeking to avoid vendor lock-in.

It wasn't worth the money.

I like the fact that it is universal as,on amazon at least, there are not many of these available unless they are for a specific model server. However, because of that the mounting options for each type of server can be limited. I had a Dell 1U server that I ended up having to mount he attachment piece on the rail instead of the server. It works well, but required some drilling and creativity. It is not super high quality but i wouldn't quite call it "cheap".
