Hammond H1TRR42U30BK 42U Tapped 10-32 Rack Rails for 30in Cabinets

The H1TRR42U30BK is a matched pair of 42U 19-inch mounting rack rails with 10-32 tapped holes on EIA spacing, sized for cabinets 30.00 in (762 mm) wide. It is part of the H1R Series of replacement and expansion rails for H1, HWF, RCK, and NWC cabinets, making it a practical choice for IT, telecommunications, industrial, and AV teams who need to replace damaged rails, add mounting positions, or change mounting style without replacing the cabinet.

The rails are manufactured from heavy-duty 12-gauge mild steel and finished in a textured black powder coat that is RoHS compliant, giving a rigid mounting platform for rack-mounted servers, network equipment, AV systems, and industrial electronics. Silkscreened 1U markings along the rail simplify equipment layout, alignment, and future expansion.

Usable mounting height is 42U / 73.50 in (1867 mm), with the drawing showing an overall rail height of 73.53 in (1868 mm) and a 19-inch mounting width of 18.35 in (466 mm). Front mounting flange detail includes 1.75 in (44 mm) 1U spacing, a 4.39 in (112 mm) top-view depth, and 4X 0.44 x 0.75 in mounting slots for attachment to the cabinet struts. H1TRR42U30BK ships as a pair and includes all required strut mounting hardware.

Holes are tapped #10-32 UNF on EIA-310 spacing, so the rails accept standard 19-inch rack equipment such as servers, switches, patch panels, UPS systems, and AV components using 10-32 screws. H1TRR42U30BK is manufactured in Canada in an ISO 9001 certified facility, is TAA compliant, USMCA compliant, and REACH and RoHS compliant.
