I've used them several times to organize DirecTV receivers, audio amplifiers, UPSs, and cable TV receivers. For the price they are great. Very heavy for 1U size. I use 12" deep. In some setups I use them to hold the rack rails together to create a sort of EQ rack. It might sound weird, but it works in places like restaurants where you need to organize things. It's not Broadcast quality, or serious networking stuff, but for most of us, it's pretty nifty and has great value.
