Hammond PBPA19007UNF 4U Unfinished Aluminum Rack Blanking Panel

The PBPA19007UNF is a 4U flat aluminum rack panel used to blank off unused rack space in 19 in EIA-compliant racks and cabinets. It is intended for IT and data centre teams, telecom installers, AV integrators and OEM engineers who need a lightweight filler panel that closes open rack openings and keeps supply and return air separated. Because it ships unfinished, it also suits custom applications where the panel will be painted, anodized, screened or labelled in-house.

Construction is 8-gauge (0.125 in) 5052-H32 aluminum, which provides lightweight durability and corrosion resistance in rack environments and makes the panel easier to handle and install than comparable steel panels. The drawing for PBPA19007UNF shows a 19.00 in (483 mm) wide panel with a 6.97 in (177 mm) drawn height, corresponding to a nominal 4U / 7.00 in (178 mm) panel height, with 0.12 in (3 mm) radiused corners. Shipping weight is 1.59 lbs (0.72 kg).

Mounting is through four 0.250 x 0.375 in slots — four mounting points total — spaced 18.32 in (465 mm) apart horizontally and 4.00 in (102 mm) vertically, so the panel drops onto standard 19 in EIA rack rails. Mounting hardware is not included and should be ordered to match your rack's rail thread or square-hole pattern.

Installing blanking panels such as PBPA19007UNF in unused rack space helps improve cooling efficiency by preventing hot and cold air recirculation, supporting thermal management strategies in high-density racks while producing a tidier, more organized installation.
