APC NetShelter 4 Post Open Frame Rack 44U #12-24 Threaded Holes

The APC AR204A is a four-post open frame rack that gives servers, switches, and telecom hardware a stable and well-ventilated home. With 44U of usable height and a static load rating of 2000 lbs, it comfortably supports dense equipment stacks without flex or sway.

An open structure makes day-to-day work easier. Technicians can reach cables, ports, and modules from any side, so moves, adds, and changes take minutes instead of hours. The design also allows unobstructed airflow, helping active cooling systems keep temperatures under control even in rooms that lack strict climate management.

Pre-threaded #12-24 mounting holes run the full length of each rail. Because the threads are already in place, you can secure hardware with the screws you use every day and skip cage nuts entirely. The standard 19-inch width aligns with most rack-mount products, and dedicated positions for vertical power distribution units let you add branch-circuits without blocking rear access.

A steel frame with a black finish stands 83.9 inches tall, 23.6 inches wide, and 29.4 inches deep. Those dimensions fit neatly in server rooms, test labs, branch offices, and edge computing closets where floor space is at a premium. Whether you are building a fresh network core or expanding an existing rack row, the AR204A provides the strength, accessibility, and compatibility that modern IT environments demand.
