Eaton SR4POST25 – 25U 4-Post Open Frame Network Rack

Product Overview

The Eaton SR4POST25 is a 25U open frame server rack built for cost-conscious 19-inch rack-mount installations in AV equipment rooms, data closets, and network staging areas. As a 4-post open frame rack for AV equipment, it provides sturdy, square-hole mounting rails without the enclosed panels of a full cabinet, which speeds up cabling and airflow access during install and service. Its adjustable depth mounting positions it as an adjustable depth network rack that can accommodate switches, patch panels, PDUs, and AV processing equipment of varying chassis depths. Multiple units bolt together side by side, making it a practical choice for a commercial AV rack for equipment room buildouts that need to scale over time.

Product Description

The SR4POST25 gives integrators a 25U mounting frame with square, numbered holes that accept standard rack-mount hardware for AV switchers, network switches, patch panels, and cable managers. Because the frame is open rather than enclosed, it is well suited to equipment rooms where front and rear access, airflow, and cable management take priority over aesthetics or security through doors. The adjustable mounting depth accommodates equipment ranging from shallow patch panels to deeper server or UPS chassis, which is useful when a single rack needs to house both AV control processors and standard-depth networking gear. Multiple SR4POST25 units can be bolted together side by side to expand capacity as an equipment room grows, without needing to replace the existing rack. This makes it a sound choice for an open frame rack for data closet spaces supporting a commercial AV deployment, where budget constraints rule out a fully enclosed cabinet but organized, secure mounting is still required. The black steel construction with toolless button holes accepts PDUs and cable managers directly, streamlining the buildout of a functional AV or IT equipment room. A compatible rack PDU can be added directly to the SR4POST25's mounting holes to distribute power to installed equipment.

Frequently Asked Questions

Can this rack hold both AV processing equipment and network switches?

Yes, the adjustable mounting depth and 25U of vertical space allow a mix of AV processors, network switches, patch panels, and PDUs in the same frame.

Does the SR4POST25 accept a rack PDU?

Yes, its toolless button holes accept PDUs directly, and Creation Networks stocks compatible rack PDUs that mount into this frame.

Can multiple racks be connected together?

Yes, multiple SR4POST25 units can be bolted together side by side, allowing an equipment room to expand capacity without replacing existing racks.

Is this rack suitable for a data closet with limited access on all sides?

The open frame design provides front and rear access, which works well in rooms with clearance on both sides; fully enclosed cabinets are a better fit for spaces requiring locked, closed panels.

What tools are needed for installation?

Basic hand tools are typically sufficient for assembly and equipment mounting; the toolless button holes simplify PDU and cable manager installation specifically.

Does Creation Networks offer installation support for equipment room racks?

Yes, our team can help plan rack layout, power distribution, and cable management for a new or expanding AV or IT equipment room.
