Review on 🔧 Installerparts 4U Hinged Extendable Wall Mount Bracket: Maximize Space with 13.5" Deep Compatibility by Stephanie Hughes

I bought another make/model and got to the point where it didn't support multiple patch panels due to the depth. Belonged to, switched to this one and it was the right decision. This one is much more durable, with rounded edges to prevent unwanted flexing. As a result, they managed to make the wire feed hole larger than my other mount. The retractable sides are great and give you extra room to sort and route your cables. When you're done, you can drag them back to the wall if your cables allow. I would buy this model first.
