PCI slot covers 5-pack black Kolink KL-PCIE-5 — metal blanking plates for expansion slots

Kolink KL-PCIE-5 is a set of five black metal PCI slot covers designed to fill unused full‑height expansion slots in standard desktop PC cases. These blanking plates restore case airflow balance, reduce dust ingress and create a uniform exterior finish when expansion cards are not installed. The set is compatible with standard ATX and similar form‑factor motherboards that use full‑height PCI/PCIe slots and includes mounting holes for standard rear panel screws.

Advantages

The metal construction provides durable protection for internal components and supports heat dissipation compared with thin plastic alternatives. Black powder-coated finish offers a low‑reflective, consistent look that integrates with most case interiors. Using slot covers helps maintain negative or positive airflow patterns set by case fans, preventing turbulent air transfer between compartments and limiting dust accumulation on components such as the CPU cooler, GPU and motherboard.

Suitable for

• Desktop PC system builds and upgrades where expansion slots remain unused
• Repairs and maintenance to protect internals from dust during storage or transport
• Custom/modular cases and small form‑factor enclosures using full‑height expansion slots
• Enclosures requiring an even exterior appearance for professional or retail presentation

Key specifications

• Quantity: 5 metal slot covers
• Compatibility: standard full‑height PCI/PCIe expansion slots (desktop cases)
• Material: metal with black finish
• Finish: black powder‑coated or painted surface
• Mounting: standard rear panel screw holes for case screws

How to use

Power down the PC and disconnect all power cables before opening the case. Remove the corresponding rear slot bracket screw, align the metal slot cover with the empty expansion slot opening, and secure it using the same screw or the case's captive screw. Reinstall the side panel and reconnect power. For stacked slots, fit covers into each unused full‑height opening to preserve airflow and prevent dust entry.

Recommendations

Inspect slot covers and mounting screws periodically during routine maintenance. If the case is used in a dusty environment, clean covers with a soft cloth and ensure screws remain tight to maintain airflow control and internal protection.
