DIGITUS DN-19 BPN-04-SW — 19" 4U Blank Panel, Black RAL 9005
4U · 19"Sheet steelBlack RAL 9005Mounting set included
The DIGITUS DN-19 BPN-04-SW is a 4U blank panel for 482.6 mm (19") network and server cabinets that closes unused rack space, keeps the front of the cabinet tidy and helps maintain front-to-back airflow. It is made from robust sheet steel in black RAL 9005 and fits all 19" profile rails.
Blank panels are one of the simplest ways to improve cooling in a cabinet: open gaps let hot exhaust air flow back to the front and into the intakes of switches and servers. A single 4U panel closes a larger gap in one piece, which looks cleaner than stacking several 1U plates.
Before you order: This panel is 4U high and black. If you only need to close 1U, 2U or 3U, DIGITUS makes other heights in the same DN-19 BPN series — check the height before ordering so it matches the gap.
What's in the Box
- 1 x DIGITUS DN-19 BPN-04-SW 19" 4U blank panel, black
- Installation set: screws, cage nuts and washers
What It Means in Practice
- Measure the gap in rack units: 4U is 177.8 mm high, the space of four standard 1U devices.
- Closing unused space stops hot exhaust air recirculating to the front, which lowers intake temperatures for switches and servers.
- Black RAL 9005 matches most black cabinets and 19" devices, so the front looks uniform.
- The panel also hides reserved space for future equipment until you need it.
What Will Not Work
- It does not fit 10" (254 mm) mini cabinets — it is for 19" rails only.
- It is not vented or brushed: cables cannot pass through it. Use a brush panel where cables must go through.
- It does not carry weight and cannot be used as a shelf.
- It will not match a light grey RAL 7035 cabinet colour.

Frequently Asked Questions
Does it fit non-DIGITUS cabinets?
Yes. It mounts on standard 482.6 mm (19") profile rails with cage nuts, so it fits any 19" cabinet or rack with square-hole rails.
Why use blank panels at all?
Open gaps let warm exhaust air flow back to the front of the cabinet. Closing them keeps cooling air going through the devices, not around them.
Can I cut it down to 3U?
It is not designed for that. Order the height you need from the same DN-19 BPN series instead.
Singular Expert Insight · Buyer's Guide
Blank panels are cheap insurance for cooling: every open U at the front is a short-cut for hot air. Close the larger gaps with a 4U panel and use smaller plates for the rest — you will find matching items in our
Rack Accessories range.
✓ Buy it if you have a black 19" cabinet with a 4U gap to close neatly.
✕ Skip it if you have a 10" cabinet, a grey cabinet, or cables that need to pass through the gap.
→ Also consider a 1U or 2U blank panel for smaller gaps, or a brush panel where cables must pass through.
