Hammond PBPA19007WH 4U Matte White Aluminum Rack Blanking Panel

The PBPA19007WH is a 4U aluminum blanking panel for standard 19 in EIA-compliant rack rails, finished in matte white (RAL9003). It is intended for IT, telecom and AV teams who need to close off unused rack space so that cooling air is directed through equipment instead of recirculating around it. Covering open U positions helps separate hot and cold air, tidies the rack face and supports a planned thermal management strategy.

The panel is formed from 8-gauge (0.125 in) 5052-H32 aluminum, a material chosen for lightweight durability and corrosion resistance in rack environments. Compared with steel panels, the aluminum construction makes handling and installation easier, which matters when a technician is working alone at the front of a populated cabinet. The smooth powder coat finish gives a clean, professional appearance across a row of racks.

Dimensionally, PBPA19007WH occupies 4 rack units with a panel height of 7.00 in (178 mm) and an overall width of 19.00 in (483 mm); the drawing shows a 6.97 in (177 mm) panel height and 0.12 in (3 mm) corner radii. Mounting is through four 0.250 x 0.375 in slots, giving 4 mounting points. Shipping weight is 1.6 lbs (0.73 kg).

For procurement, this part is TAA-compliant and manufactured in North America, with country of origin CA and USMCA compliance. It is RoHS and REACH compliant, classified under ECCN EAR99 and tariff code 8538.10.0000. Mounting hardware is not included, so specify rack screws or cage nuts to suit your rails. The PBPA Series is offered in matte black, dark gray, light gray, matte white and unfinished aluminum, and in heights from 1U through 10U, so PBPA19007WH can be mixed with other sizes to fill any remaining openings in a rack.
