The ADA-1250 is going to be a snug fit in my plastic equipment rack. I measured it yesterday and 18" is the maximum width. The ADA-1250 is 17.75" wide.

There is only a pole in each corner, so there will be plenty of ventilation. The whole thing is in a closet with sliding doors shut with a 1 inch gap, to keep the cat out.

Probably ought to start thinking about a ventilation fan.
