Tripp Lite 50U Heavy-Duty 4-Post SmartRack Open Frame Rack, Organize and Secure Network Rack Equipment

The Tripp Lite SR4POST50HD is a rack that features a heavy duty design with four posts and an open frame, built to accommodate 50U of standard 19-inch equipment. It uses cold-rolled steel with a black powder coat finish and carries up to 3,000 pounds of stationary gear, so it can handle dense server stacks, storage arrays, or large switches without flexing.

Because the frame is open on all sides, airflow is unobstructed and cables stay easy to reach. Numbered square-hole mounting positions run the full height, which speeds up alignment when you are sliding in servers or network appliances. Depth adjusts out to 35 inches, giving you enough room for deep chassis or rear cable management arms. Toolless button holes let you add Tripp Lite PDUs and cable managers without extra hardware, a detail that many datacenter technicians appreciate during rapid build-outs.

Self-squaring posts and included bolts make assembly straightforward for a single installer. Once the frame is on the floor, anchor points allow a solid bolt-down to concrete, or you can add the optional SRCASTERHDKIT caster set when mobility matters, such as in lab environments where racks move for reconfiguration. Optional SR50SIDE4PHD side panels finish the look at the end of a row and help guide airflow when hot-aisle or cold-aisle strategies are in place.

This rack fits naturally in corporate data centers, network closets, campus IT rooms, and test labs that demand strong load support, fast access, and simple cable routing.
