Installing the cable box behind the TVs in a commercial environment(lobby/fitness of a residential building). Is there a in wall/recessed swivel mount that can be locked? Doesn't need to swivel; just needs to come out enough for access to the cable box in the media enclosure. The enclosure will lock anyway; just curious if such a thing exists. Kind of like this but in wall:

I can probably add something to lock it but it would be nice to get it premade.

Chief PAC501B and PNRIWUB mount. Has a place to be able to put a padlock. Will at least keep the honest people from taking it.

How would you put a padlock? Just to clarify, want to be able to prevent unauthorized personal from extending the mount since the cable box and switch will be next to in in another box. So far I am leaning towards the versabox mounts from s#*p since they are smaller and can fit the mount and the backbox behind the TV.

The padlock only keeps the TV from being removed from the mount and stolen. It won't keep it from being pulled out.
