AtlasIED 221-25 25.5-Inch Welded Rack, 21RU, Front Door Not Included
The AtlasIED 221‑25 is a deluxe 21RU floor-standing rack cabinet optimized for professional audio, IT, broadcast, and security installations. Built from rugged 16-gauge cold-rolled steel and finished with textured black epoxy, this welded cabinet ships fully assembled—base, top, side panels, adjustable rails, and rear door—ready for immediate deployment. Its expanded 25½″ depth delivers extra internal space for bulky equipment.
Installation is streamlined with a quick-release rear door featuring a cylinder lock and 180° swing capability. Adjustable 11-gauge CRS mounting rails are tapped for 10‑32 and recessed 11/16″, complete with RU indicator hash marks for precise gear mounting. With a 6RU openable top and bottom, dual conduit knockout arrays, and perforated vented panels on all sides, the cabinet ensures effective cable management and air convection for equipment cooling.
