1U Rackmount Cable Management Rings

Update 11/11/20: Added V2 with reinforced corners.

A collection of a few cable management rings for network racks. All rings mount in a 1U space and can be mounted over the top of patch panel and switch rack ears.
The spacing between the hooks is just enough to slip a CAT5/CAT6 cable through, but prevent it from coming back out. I have included three different options.

1U_Cable_Ring_Front - Works well for mounting to the front of the rack over patch panels and switches for routing cables to the side of the rack.

1U_Cable_Ring_Side - Works well for mounting on the rear rail of the rack for managing
incoming infrastructure cabling.

1U_Cable_Ring_Vertical - Works well for mounting at a couple points in the front, rear or side of rack for running vertical cables between patch panels and network devices.

I was able to fit right at 24 CAT6 cables inside a single ring.

EDIT: Added an inverted version of the vertical cable ring for all my OCD friends out there,
