Cell phone storage bins

[HuggyU2]

Odd request...

When you go into a classified briefing room, there's usually a storage bin into which many people put their cell phones before they enter the room.  Most of the ones I've seen are poorly designed.

If you have a picture of a wall-mounted unit that is exceptionally well designed, would you send me a link to where you got it, or at least a photo of it with the dimensions of the storage slots.

I hate those things, and they are marginally effective unless the walls of the briefing room are shielded/tempested.

However, a design like this would work better than the ones I usually see (small lockers) if it had individual doors...
