StarTech.com 2.4 x 3.9in Vertical Cable Management D Ring - 1.5U Metal D-Ring Hooks - Wire Organizer for 2 or 4-Post Network/Server Racks (CMHOOKMW) Black

I have a 42u server rack in my basement with about 8 servers. These worked great for routing a/c power cords up to the servers. I also used these to hold a service loop from my patch panel to the servers. Will buy more of these in the future. Have already recommended these to friends.

I needed cable management solution to move a bundle of 24 Cat6 cables from one patch panel to another about 10 feet away in a residential installation. These worked great mounted to the drywall with toggle screws, the kind with the white plastic toggle you screw into the wall, then insert a metal screw in (with a washer). Finish on these D-rings is great and there are no sharp edges. I'd estimate you could easily put two bundles of 24 Cat6 cables each in the 2.2x3.9 D-ring, maybe more if they're not in bundles.

I purchased these to go at the top of each side of the back of my full size server racks. One at the (nearly) top left and one at the (nearly) top right. Even though some reviewers believe it is over priced for what it is, I can say that:Pros:Substantial MaterialDesigned well in that it offers multiple mounting configurationsProvides the expected resultCons:Perhaps they are a tad overpricedHowever, the other vertical cable management options for server racks that I've considered are significantly more expensive.I liked the results of having these manage the power and network cables that I've purchased 2 more for another cabinet I'm building out soon.

I have one of these at the back of my FX rack as a sort of a conduit to keep cables out of the way. It's nice to have the mounting holes in two planes so you can orient it whichever way you want. The bracket can be bent with a bit of force and won't take a lot of abuse. It's bigger than it looks, the rectangular shaped bracket area is about the size of a slice of bread so will fit many cables inside (a few at a time, they won't all fit through the opening at once). Pricey for what it is but I've found it useful.

These are very sturdy, they could probably hold more than cable, I used a bunch of these in the back of my server rack to route and hold external cables vertically, keeping them seperate from "internal" cables contained within the rack. Buying a few more.

Good quality material, no sharp edges.Mounting holes are an odd choice, and prevent use around equipment. If they were punched for each hole in a U, it would probably weaken them some, but would allow for integration with existing, used mount points.

This vertical cable management is great for the sheer amount of cables it can hold. I managed to hold 96 cat 5e cables within the hooks with plenty of room to spare. It may not look as good as the cable management with the fingers but it is a fraction of the cost and it fits my rack better. My only gripe is it does not come with mounting hardware for the older screw racks and the cost. It only comes with cage nuts. It is almost double the price of other vertical hooks.

I wall mounted these in sheetrock (drywall) in my wiring closet to manage 13 pairs of 16g speaker cables, a few TOS links and a few pairs of Ethernet (thin cat 6). Use the right kind of screws for your application (not included) and be happy. These are a good, low cost solution for smaller cable runs instead of installing a ladder. Perfect for my application.
