The solution is made possible by custom cutting the face of the rackmount unit to work perfectly with the piece of equipment that you specify. The result is a neatly trimmed installation, with a snug fit and no gaps. Middle Atlantic has more than 8,000 components in its measurement database that can be matched with this unit.

A ventilated bottom on this unit ensures adequate cooling. The included rear brackets prevent the mounted component from sliding out the rear of the enclosure.
