The RSH-4A Custom Rackmount Enclosure (Black Brushed and Anodized) from Middle Atlantic is a flexible solution that lets you mount virtually any non-rackmount component in a standard 19" rack or enclosure without making any modifications.

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.
