Hammond H1SRR52U30BK 52U Square-Hole Rack Rails for 30in Cabinets

The H1SRR52U30BK is a matched pair of 52U square-hole 19-inch mounting rails from the H1R Series, intended for owners of H1, HWF, RCK and NWC cabinets who need to replace damaged rails, add mounting positions, or convert a cabinet from threaded to square-hole mounting without replacing the enclosure. This version is configured for 30.00 in (762 mm) wide cabinets.

Rails are manufactured from heavy-duty 12-gauge mild steel and finished in a textured black powder coat that is RoHS compliant, providing a rigid mounting platform for rack-mounted servers, network equipment, AV systems and industrial electronics. Square holes are 0.38 in on typical EIA spacing, so the rails accept cage nuts and standard square-hole rack hardware, and EIA-310 square-hole mounting means compatibility with virtually any standard 19-inch rack equipment.

Usable mounting height is 91.00 in (2311 mm), giving 52 rack units, with the drawing showing an overall rail length of 91.03 in (2312 mm) and an 18.35 in (466 mm) 19-inch mounting width. Each rack unit is marked in 1.62 in (41 mm) increments, and silkscreened U markings on the rails simplify equipment installation, alignment and future expansion.

H1SRR52U30BK ships as a pair and includes all required strut mounting hardware for straightforward installation into a compatible cabinet. Rails also feature 4X 0.44 x 0.75 in mounting slots as shown on the part drawing.

The part is manufactured in Canada in an ISO 9001 certified facility, is TAA compliant, USMCA compliant, and RoHS and REACH compliant, making H1SRR52U30BK suitable for IT, telecommunications, industrial and AV projects with sourcing requirements.
