Works for hiding cables
Color: Black, Size: Standard
Worked great to manage my cables to my pc setup. My double wide surge protector fit in there just right. Easy to mount with the holes and the bottom to fit a screw driver or power drill. Not too flimsy.

High quality, reliable
Model: Pop up outlet-black
The units looked really cool and were of excellent quality. They popped up reliably albeit slowly which was fine with me. I was really looking forward to using these in a built in cabinet we're making but they did not fit where I wanted them so I had to send them back. I would buy these again if I ever had a project that needed them.
