The PLRSTN22U from Pyle Pro is a 2 RU rackshelf designed for mounting small components in rack enclosures contained in houses of worship, concert venues, recording facilities, A/V installations, server rooms, and more. It attaches easily to standard 19" equipment racks and works with both non-rack and half-rack gear. The pre-cut holes allow universal device placement and air circulation to keep equipment cool. The sturdy steel construction can hold up to 110 lb on the 14.7"-deep shelf.
