The Pelco RMA14T Rack Mount Adapter is a 8RU (~14") height rack adapter, used to hold a single Pelco PMCS14A professional broadcast monitor within a rack.
The RMA14T has a fixed position for the monitor, keeping it flush with the face of the rack. Though it consumes 8RU of rack space, it is actually a fraction smaller than that full allotment of space-there will be a very small gap between adjacent items when installed in the rack.
