Hammond RCHR1908 5U Round Hole Rack Mount Rails, Pair

The RCHR1908 is a pair of 5U round-hole formed rack mount rails made as factory replacement or add-on mounting rails for Hammond RCH cabinet systems. It suits IT and telecom technicians, AV integrators, OEM engineers and facilities teams who need to replace damaged rails, restore an existing cabinet, or add a second pair of mounting positions inside a cabinet that uses an 8.75 in (222 mm) panel height.

Each rail is formed from 16-gauge mild steel for a rigid mounting platform and is finished in a textured RAL 9005 black powder coat for corrosion resistance and a consistent appearance with the cabinet interior. The round-hole mounting pattern is EIA-310 compliant and accepts standard 19-inch rack equipment using clip nuts and 10-32 rack screws; rack mounting hardware is sold separately, while cabinet mounting hardware is included.

Drawing dimensions for RCHR1908 give an overall rail length of 8.75 in (222 mm) with 8.25 in (210 mm) of EIA spacing, equal to 5 rack units. Round holes measure 0.28 in (7 mm) diameter typical on the standard EIA pattern of 0.62 in (16 mm), 0.62 in (16 mm) and 0.50 in (13 mm). Two 0.281 x 0.688 slots per rail are provided for attachment to the cabinet.

RCHR1908 ships as a matched pair with a shipping weight of 1.41 lbs (0.64 kg). The rails are manufactured in North America (country of origin CA) in an ISO 9001 certified facility, and are TAA-compliant, USMCA compliant, RoHS compliant and REACH compliant.
