Description
The Tripp Lite by Eaton SR4POST50HD is a 50U heavy-duty 4-post open frame rack designed for high-density IT, networking, and data center environments where secure airflow and easy equipment access are essential. Built from rugged cold-rolled steel with a black powder-coated finish, this open rack supports up to 3,000 lb of stationary equipment.
Its open-frame design provides unobstructed airflow and simplified cable management, making it ideal for servers, switches, UPS systems, and patch panels. Numbered square-hole mounting rails ensure fast and accurate installation of standard 19-inch rack equipment, while adjustable depth support accommodates devices up to 35 inches deep.
Designed for flexibility, the SR4POST50HD features a self-squaring frame, bolt-down provisions for permanent installations, and toolless button-hole mounting for vertical PDUs and cable managers. Multiple racks can be bolted together side-by-side for scalable, high-density deployments.
