13U open frame rack for 19 inch equipment

The Tripp Lite SR4POST13 is a 13U four-post open frame rack built from black cold-rolled steel. It provides standard 19 inch mounting with square, numbered holes for rackmount servers, switches and patch panels. Multiple units can be bolted together side by side to expand capacity. The rack supports up to 1000 lbs of installed equipment.

Thermals noise and power

As a passive steel frame the rack generates no noise and draws no power. Open sides allow unrestricted airflow around mounted devices so cooling depends entirely on the equipment installed inside. The black finish does not add measurable thermal resistance. No fans, power supplies or active components are included.

Toolless PDU and cable manager mounting

Button holes on the frame accept power distribution units and cable managers without tools, reducing installation time. Square mounting holes accept cage nuts for quick hardware changes. The rack ships unassembled and weighs 43 lbs for handling by one or two people. No shelves, rails or cable trays are bundled.

Questions about this item

How do I bolt multiple SR4POST13 racks side by side, and which holes do I use?

Align the frames and use the square mounting holes on the vertical rails to bolt units together; the holes are numbered so you can match height positions across racks.

Will the square mounting holes or toolless button holes wear out if I swap PDUs or cable managers often?

The square holes are cold-rolled steel and the toolless button holes are stamped into the same material; both are designed for repeated insertions without thread damage.

At what load does the 1000 lb rating become the limiting factor during continuous operation?

The 1000 lb capacity is a static structural limit; as long as the combined equipment weight stays at or below that figure, the rack frame remains within its rated limit.
