Hammond H1TRR45U30BK 45U Tapped 10-32 Rack Rails for 30in Cabinets

The H1TRR45U30BK is a matched pair of 45U 19-inch mounting rails with 10-32 tapped holes, engineered as replacement or expansion rails for Hammond H1, HWF, RCK and NWC cabinets built on a 30.00 in (762 mm) overall cabinet width. It is intended for IT and telecommunications teams, AV integrators, industrial panel builders and facilities staff who need to restore, add or reconfigure rack mounting positions inside an existing cabinet rather than replace the cabinet itself.

The rails are formed from heavy-duty 12-gauge steel in mild steel, finished in a textured black powder coat (painted thin film black) that is RoHS compliant and gives a durable, professional appearance. Silkscreened 1U markings run the length of each rail to simplify equipment alignment, patch panel layout and future expansion planning.

Usable mounting height is 45U — 78.75 in (2000 mm) — with an overall rail height of 78.78 in (2001 mm) and a 19-inch mounting width of 18.35 in (466 mm) on standard EIA spacing at a 1.75 in (44 mm) rack unit pitch. Holes are tapped #10-32 UNF throughout, so equipment mounts directly with 10-32 screws without cage nuts. Rail flange dimensions include 4.39 in (112 mm) and 2.00 in (51 mm) profiles per the drawing, with 4X 0.44 x 0.75 in slots for strut attachment.

H1TRR45U30BK ships as a pair and includes all required strut mounting hardware for straightforward installation. If square-hole EIA-310 mounting is preferred instead, the matching square-hole version of this size is H1SRR45U30BK. The part is TAA-compliant, USMCA compliant, REACH compliant and manufactured in Canada.
