StarTech.com RKPNL4U — 4U Solid Blanking Panel for 19" Racks
4USolid steel19" EIA-310-DM6 hardware included
The StarTech.com RKPNL4U is a 4U solid steel blanking panel that closes an unused gap in a 19" server or network rack, keeping hot exhaust air from recirculating to the front of your equipment and giving the cabinet a clean, finished front. It is aimed at anyone running switches, servers or UPS units in a rack with empty positions between devices.
Blanking panels are one of the simplest airflow fixes in a rack: without them, cooling fans pull warm air back through open gaps instead of drawing cool air from the front. A single 4U panel covers a large gap in one piece, and the powder-coated black finish matches most modern cabinets.
Before you order: 19" racks only. The supplied hardware is M6 screws with M6 cage nuts, which suits square-hole rails; for threaded or round-hole rails use screws that match your rack.
What's in the Box
- 1 x 4U solid blanking panel (black steel)
- 4 x M6 screws
- 4 x M6 cage nuts
What It Means in Practice
- Covers four rack units (177 mm) in one piece — fewer panels to fit than using 1U blanks.
- Stops hot-air recirculation through empty positions, helping switches and servers run cooler.
- Solid face hides empty space and cabling behind it for a tidier, more professional front.
- Everything needed for a square-hole rack is in the box, so it fits straight away in most cabinets.
What Will Not Work
- Will not fit 10" racks or wall brackets narrower than 19".
- Not vented — do not use it where you deliberately want air to pass through the front.
- Does not route or hold cables; it is a cover, not a cable manager.
- The M6 hardware will not suit 10-32 threaded rails; use your rack's own screws there.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
Blanking panels are the most overlooked part of a rack, yet they are the cheapest way to lower intake temperatures in a closed cabinet. A 4U solid panel is ideal for the gap left above a UPS or below a switch stack, and because StarTech includes the M6 hardware there is nothing else to order for a standard square-hole rack. For smaller gaps or brush-entry panels see our rack accessories range.
✓ Buy it if you have a 4U empty space in a 19" rack and want to improve airflow and appearance.
✕ Skip it if you need cables to pass through the front — choose a brush panel instead.
→ Also consider StarTech.com CMDUCT1UX 1U covered cable duct, or 1U/2U blanking panels for smaller gaps.
