Hammond H1SRR36U24BK 36U Square-Hole Rack Rails for 24-Inch Cabinets

H1SRR36U24BK is a matched pair of 36U, 19-inch panel mounting rails with EIA-310 square holes, sized for 24.00 in (610 mm) wide cabinets. It is intended for IT, telecommunications, industrial and AV users who need to replace damaged rails in an existing H1, HWF, RCK or NWC cabinet, add mounting positions, or convert a cabinet from 10-32 threaded mounting to square-hole (cage nut) mounting without replacing the cabinet itself.

The rails are formed from heavy-duty 12-gauge mild steel and finished in a textured black powder coat that is RoHS compliant, giving a rigid, durable mounting platform for servers, switches, patch panels, UPS systems and industrial electronics. Square holes are 0.38 in on typical EIA spacing, and silkscreened 1U markings run the full height of each rail to simplify equipment alignment and future expansion.

This 36U version provides 63.00 in (1600 mm) of usable mounting height, with an overall rail height of 63.03 in (1601 mm) per the drawing, and mounts across a 24.00 in (610 mm) cabinet width. Each rail carries 4X 0.44 x 0.75 in mounting slots, and all required strut mounting hardware is included, so installation is a straightforward bolt-in job. Shipping weight for the pair is 20 lbs (9.07 kg).

H1SRR36U24BK is manufactured in Canada in an ISO 9001 certified facility, is TAA compliant and USMCA compliant, and meets RoHS and REACH requirements. The rails accept standard 19-inch rack equipment, keeping refurbished or reconfigured cabinets fully compatible with the hardware already in service.
