I'm working on getting an 85" Frame installed in a university library, and they want a small lockable cabinet to store the OneConnect box so students can't get to it. Ideally they would prefer something like a wooden cabinet with legs so it's raised up off the floor a few inches, but they're willing to consider a wall-mounted option too. The walls are cinder block so they can't use an in-wall box, unfortunately.

I've been searching on places like Grainger and Uline, as well as Home Depot and even Amazon, and can't find anything that's small and simple.
