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.
