StarTech RKPNL4U — 4U Rackmount Blank Panel (Steel, Black Powder‑Coated)

Open rack bays are a thermal and dust problem waiting to happen — the RKPNL4U blanks four units at once, directing cooling airflow where it belongs and keeping the rack looking clean and professional in any data center or wiring closet.

The StarTech RKPNL4U is a 4U rackmount blank filler panel designed to cover unused rack spaces, improve airflow, and maintain a clean, professional appearance in server rooms, AV racks, and network cabinets. Constructed from solid steel with a durable black powder-coated finish, this panel provides long-term rigidity and a polished, uniform look across your rack.

Ideal for data centers, IT closets, AV installations, and structured cabling environments, the RKPNL4U helps reduce dust buildup, optimize cooling efficiency, and protect internal equipment by closing open rack units.
