Wire Hooks VEVOR 4 Post Open Frame Server Rack

Needed some hooks for running cables and not just letting them hang in the back and didn't want to buy additional wire management accessories. Fits around the 30mmx40mm portion of the top rails. I am sure this will fit others, but I specifically have the VEVOR server rack I got on eBay. The slots in the hooks are intended for small strips of velcro (may have to cut) or twist ties (recommended using velcro).
