Review on 🔧 StarTech.com 8U Open Frame Wall Mount Network Rack with Built-in Shelf - Adjustable Depth (12" to 18") 2-Post Equipment Rack, 75.2lbs - Black (WALLSHELF8U) by Chris Thrower

Used in my basement for Unifi Rack Switch, Power Panel, Keystone Panel and Unifi USG, Cable Modem and Raspberry Pi (everything on the shelf). It works great and is very durable. The mounting holes fit 16" OC wall studs. I installed 1/2" washers between the stud and the wall and bought some longer 2-1/2" screws to make sure everything was secure. Spacers allow for it allows you to route cables from the ceiling behind the counter and through the rear opening into the keystone panel.
