Eaton SR2POST25 – 25U 2‑Post Open Frame Rack

Overview

The Eaton SR2POST25 is a two‑post, open‑frame rack designed to mount standard 19‑inch rack‑mount equipment where a full cabinet enclosure is not required. It is typically deployed by network architects, datacenter technicians, and IT infrastructure teams in network closets, branch office environments, telecom rooms, and edge cabinets where equipment density is moderate and cable accessibility and airflow take priority. Its open design facilitates easy access to cabling, ports, and airflow paths.

This rack frame provides 25 rack units (25U) of usable vertical space — enough for network switches, routers, PDUs, lightweight servers, patch panels, and cable managers. The vertical rails are 19‑inch EIA‑310 standard and use #12‑24 threaded / numbered mounting holes for consistent rack hardware alignment, ensuring compatible installation of rack equipment and accessories.

Constructed from heavy‑duty aluminum with a textured black powder‑coat finish, SR2POST25 balances structural strength with minimal weight. Its self‑squaring design and bolt‑down provisions simplify setup on raised floors or solid surfaces. Tool‑less button‑hole provisions support vertical PDUs or cable management accessories without additional hardware.

SR2POST25 integrates into structured environments compliant with EIA‑310 and IEC 60297‑3‑100 standards, allowing seamless use of standardized 19″ rackmount gear. It is compatible with ancillary accessories such as vertical cable managers, horizontal cable rings, and vertical PDUs that mount to two‑post rack uprights.

In practice, this rack suits network distribution closets, lightweight server edges, and test labs. It is not recommended for heavy equipment (e.g., full 4‑post servers or large UPS systems) without additional support brackets or shelves, as the open‑frame format inherently offers less lateral rigidity than four‑post cabinets.
