Hammond HWC3018USR 18U Square-Hole Mounting Rail Pair, 30in Wide Cabinets

HWC3018USR is a pair of 18U square-hole mounting rails sized for 30-inch-wide HWC Series swing-out wall-mount rack cabinets. It is intended for IT, AV and telecom installers who need cage-nut style mounting instead of the tapped 10-32 rails supplied with the cabinet, or who want an additional rail pair for front-and-rear or intermediate equipment support inside a 30-inch-wide HWC enclosure.

The rails are fabricated from mild steel with a black painted thin film finish, and are sold as a pair (quantity 2 per item). Each rail carries square holes on typical E.I.A. spacing, with square-hole cutouts sized for cage nuts so 19-inch equipment can be mounted with standard cage-nut and screw hardware. The rails also include a cable pass-through and a cutout for 1U mounting, supporting organized cable routing and optional 1U 19-inch accessories such as cable management and power distribution.

Key drawing dimensions for HWC3018USR include a rail height of 31.00 in (787 mm) covering 18U of mounting space, a 19-inch mounting reference of 18.35 in (466 mm), and 1.75 in (44 mm) rack-unit increments. Shipping weight for the pair is 6.9 lbs (3.13 kg).

Within the HWC Series, the 10-32 threaded rails are field-replaceable and can be swapped for square-hole rails, which is exactly the role this part fills. Per the series ordering data, HWC3018USR is the square-hole rail option for 18U cabinets in the 30-inch width; HWC3018UTR is the tapped 10-32 equivalent.
