5 Pieces of 1.7 x 2.7in Server Rack Cable Management D-Ring Hooks - Network Rack-Mount Cord Organizer Ring Set for Power Cords, Fiber Optic or Network Patch Cables (5DRing)

These are so nice but I never use them for server rooms, I just use them for furniture. I wish they made a smaller version of them (keeping the screw holes the same size) but just reducing the depth and height by half.

These are good and simple and sturdy. They are not the Rittal versions that I like so much, but they're just fine.Some racks will have places specifically for these, while some others may have random types of holes and squares all over the place for cage nuts, but it's amazing how many places they don't fit considering there are multiple options just on the hooks.But one thing for sure is that you can use them for cable management on the walls if you have (hopefully fire-retardant) plywood in place. This is a common setup in TCs that I see, and I also have a setup like this in my house's TC. Very useful, and you can use them to tie up the cables to help take the vertical weight off as well.

I used these hooks to corral the power cables in my V7 12U (enclosed) server rack. These were easy to attach once I figured out the best approach to mounting them. Admittedly that was a bit of an issue with the enclosed server rack since I was limited with the angles I could mount these. Wound up attaching them to the back vertical rails facing forward and stringing the cables through there. Overall they work, however I detracted one star since this set did not come with mounting screws or cage nuts. The ones I have on hand are M6 sized and did not fit the smaller holes, though the bigger holes worked fine. Just something to keep in mind when ordering these. Otherwise, they helped with my cable management issue

These were very handy additions to my network rack. They were an excellent addition to my network switch cable management. For the price, they are a great value for cleaning up long and unsightly Ethernet cables.

Sturdy set of serious metal D rings for cable management. These are sturdy metal holders with a nice smooth coating and plenty of hold space for my rack cable management. I was a little surprised there was no hardware, but I have loads of cage nuts and screws in my preferred size, so it is actually better for me this way. These are definitely worth a buy if you are setting up or organizing a rack.

I was a little skeptical at first of these hooks, as the price seemed too good to be true, and I also was curious exactly how these were going to attach to my server rack.For reference my server rack is a 32U, 4-post, open frame. Found a couple of spots where these hooks came in handy to manage some cable runs that were running down/up the sides of the rack. They attach straight to the uprights taking up 1U space. Although, as you can see from the pictures, I elected to use them on the backside of the front posts. Attached them with rack studs as that's my typical securing method within the rack, although, I could see using cage nuts/bolts to not have the nuts sticking out into the area where the cables are. I don't have many cables running through the hooks, so it's not an issue in my case, but if you had a 40-50 ethernet buddle running through the hook, then you'd probably want the extra room.I didn't attempt to mount them in the other orientation as I am not exactly sure how I'd do that, but there are holes to do it.Overall, if you're looking for a way to neatly run cables horizontally in your rack then this would be a great product.

These work perfectly for my use-case. I was a little skeptical going with these at first because of the low price and lack of reviews. The metal is thin and bends easily by applying pressure with your thumb and index and the colors a nice matte black just like all your other rack gear.I’ve been in the process of moving some rack equipment out into the garage. It’s either older or low cost value equipment. To give these a proper test I took several strands of cat6 (because I don’t have nowhere near 50 cables in my rack). Looped them to turn 3-4 strands and run 30+ cables inside it. Tied 1 end and let the force of the cables trying to spread against the ring do their thing. In the end, this D ring held them just fine.

Nice set of hooks to tidy up your rack. Not as thick and heavy and some other brands, but great value and they are perfect for most peoples needs.No screws or cage bolts included. From my experience, most people have a a bunch lying around anyway.
