Hammond C4PR7723SZPL 44U 23-Inch Square-Hole Cabinet Rail Pair

The C4PR7723SZPL is a factory-engineered pair of 44U rack mount rails with EIA-310 square-hole mounting on a 23-inch panel width, intended for Hammond C4, C4RR_S, C4RR_A, C4RR_D and DCZ4 cabinet systems that are 30.00 in (762 mm) wide. It is the part to specify when replacing damaged rails, adding mounting positions, or converting an existing cabinet from 10-32 threaded to square-hole mounting for telecom, utility and industrial equipment built to the 23-inch standard.

Square-hole rails in the C4PR Series are manufactured from 12-gauge steel for a rigid mounting platform suitable for servers, switches, storage equipment, UPS systems and other rack-mounted devices. The finish on C4PR7723SZPL is zinc plating, which provides corrosion resistance while improving electrical grounding continuity through the cabinet. The base material is mild steel, and the rails carry silkscreened 1U markings to simplify equipment layout and future expansion.

Mounting width is 23.00 in (584 mm) with an overall rail height of 77.03 in (1957 mm), giving 44 rack units of usable mounting space. The square holes accept 10-32, 12-24, 1/4-20 and M6 cage nuts, so the rails work with virtually all modern rack hardware. As a 30-inch cabinet rail, this model includes integrated cable management features: cable tie slots and a 3.00 x 1.00 cable pass-through cutout for routing bundles without consuming equipment space.

C4PR7723SZPL is sold in matched pairs and includes the required strut mounting hardware. The part is made in Canada, is TAA-compliant for GSA Schedule purchases, and is RoHS, REACH and USMCA compliant.
