Hammond H1TRR45U24BK 45U 10-32 Tapped 19-Inch Rack Rail Pair

H1TRR45U24BK is a matched pair of 19-inch panel mounting rails with 10-32 tapped holes, providing 45U of usable mounting space in 24.00 in (610 mm) wide cabinets. It is intended for IT, telecommunications, industrial and AV users who need to replace damaged rails, add mounting positions, or reconfigure an existing H1, HWF, RCK or NWC cabinet without replacing the cabinet itself.

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, durable mounting platform for rack-mounted servers, network equipment, AV systems and industrial electronics. Silkscreened 1U markings run the length of the rail to simplify equipment alignment, installation and future expansion.

Hole spacing follows EIA spacing with tapped #10-32 UNF holes throughout, so the rails accept standard 19-inch rack equipment such as servers, switches, patch panels, UPS systems and AV components. If square-hole mounting is preferred instead, the same 45U size in a 24 in wide cabinet is offered as H1SRR45U24BK.

Usable mounting height is 78.75 in (2000 mm) / 45U, and the drawing shows an overall rail height of 78.78 in (2001 mm) with a 24.00 in (610 mm) cabinet width dimension, a 29.19 in (741 mm) depth-related dimension and 77.19 in (1961 mm) front-view dimension. Each rail includes four 0.44 x 0.75 in mounting slots, and all required strut mounting hardware is included.

• Sold as a pair, with 10-32 tapped holes and silkscreened U markings
• Made in Canada, TAA-compliant and USMCA compliant, RoHS and REACH compliant

H1TRR45U24BK is a factory-engineered replacement and expansion part for cabinet refurbishment and custom cabinet configurations.
