Hammond CPRSA Set of 4 Square-Hole Rail Shelf Adapters, Steel

The CPRSA is a panel rail shelf adapter kit that lets compatible Hammond fixed shelves mount securely to CPR Series square-hole rack rails. It is aimed at IT and data centre teams, telecom installers and control-panel builders who are standardizing on square-hole rails but want to keep using shelving originally designed for threaded rail systems.

Each CPRSA kit is supplied as a set of four (4) rail adaptors with the required mounting hardware included, so one kit provides everything needed for a single compatible shelf installation. The adapters are formed from heavy-duty 14-gauge mild steel and finished in black, providing a rigid mounting interface between the shelf and the square-hole rail. The drawing notes a painted black textured finish, while the series description specifies a durable smooth black powder coat for long-lasting corrosion resistance.

Per the part drawing, each adapter measures 1.75 in (44 mm) high by 0.75 in (19 mm) wide with a 1.38 in (35 mm) deep side profile and a 0.77 in (20 mm) flange dimension. Six 0.25 in (6 mm) diameter holes and a 0.375 in square cut-out on typical EIA spacing align the adapter with the rail and shelf hardware. Shipping weight is 2 lbs (0.91 kg).

The simple bolt-on design installs quickly and works with Hammond RFVS, RFUS, RZVS and RASC shelf series, so existing shelves can be reused after a cabinet rail upgrade rather than replaced. CPRSA is manufactured in North America (Country of Origin: CA) in an ISO 9001 certified facility, is TAA compliant and USMCA compliant, and meets RoHS and REACH requirements.
