48U Open Frame Server Rack

The Tripp Lite SR4POST48HD is a floor-standing 4-post open frame rack providing 48U of mounting space for standard 19-inch equipment. It is built for IT managers organising high-density server and networking gear in secure environments that do not require lockable doors. The heavy-duty cold-rolled steel construction supports stationary loads up to 3000 lbs.

Passive Airflow and Structural Load

The open frame design allows unobstructed airflow around installed devices without integrated fans or active cooling systems. Structural stability comes from the heavy-duty steel frame rated for 3000 lbs stationary weight and self-squaring assembly with bolt-down provisions for floor anchoring. Multiple units can be bolted together side by side for expanded capacity.

Numbered Mounting and Expansion Options

Numbered square-hole mounting positions simplify alignment and installation of 19-inch rack equipment supporting depths up to 35 inches. Toolless button-hole mounting accommodates vertical PDUs and cable managers without extra hardware. An optional heavy-duty rolling caster kit adds mobility while maintaining the 3000 lb rolling load rating, and all assembly hardware is included.

Questions about this item

How do I assemble the 48U open-frame rack and what step is most often missed?

Use the included hardware to build the self-squaring frame, then tighten all bolts fully; the step most often missed is anchoring the bolt-down provisions to the floor before loading equipment.

What parts will need replacement or maintenance over time?

The rack itself has no consumable parts; only the optional heavy-duty caster kit may require wheel replacement after extended rolling use.

What is the first limit reached when the rack is fully loaded and stationary?

The 3000 lb stationary weight capacity is the first hard limit; equipment depth must also stay within the 35 inch maximum supported depth.
