Hammond PA3UWH 3U 23 to 19 Inch Rack Rail Reducer, White

The PA3UWH is a 3U rack rail width reducer panel that adapts 23 in or 24 in rack rails to accept standard 19 in rackmount equipment. It is aimed at IT and network integrators, telecom technicians and facilities teams who need to install 19 in hardware into wider telecom or legacy racks without modifying the rack or replacing it. The part is supplied in pairs, giving complete left and right rail adaptation.

Construction is 14-gauge mild steel for durable structural support in rack width conversion applications, finished in a matte white powder coat to RAL9003. The powder coat finish is GREENGUARD, TSCA and RoHS compliant, and rounded corners reduce sharp edges during installation. PA3UWH is RoHS, REACH and USMCA compliant, TAA-compliant, and manufactured in North America (country of origin CA) within an ISO 9001 certified facility.

This 3U version provides 5.25 in (133 mm) of mounting height, with a drawing overall height of 5.22 in (133 mm), a 4.75 in (121 mm) front dimension and a 3.12 in (79 mm) depth. Equipment mounting holes are EIA-compliant 10-32 tapped for standardized, secure installation, and 0.250 x 0.375 oblong slots are provided for attachment to the rack rails.

• 3U height for equipment up to three rack units per reducer pair
• 10-32 tapped holes on the 19 in mounting face
• 12-24 x 5/8 in mounting screws supplied (qty 4)

Use PA3UWH where rack standards are mixed — central offices, data centers with both 23 in and 19 in rails, and legacy rack upgrades — to integrate IT hardware cleanly and avoid costly rack replacement.
