PCI Slot Blanks Akasa AK-MX302-KT05 — Pack of 5, Full-height Metal Slot Covers

Akasa AK-MX302-KT05 PCI slot blanks are a set of five full-height metal slot covers designed to fill unused PCI and PCIe expansion openings in standard ATX-compatible desktop computer cases. Each metal cover restores the case's rear panel continuity, helps preserve internal airflow patterns, reduces dust ingress and maintains chassis grounding where blanking plates are required. The covers are intended for installation in full-height expansion slots and provide a low-profile, durable alternative to makeshift fillers.

Advantages

The full-height metal construction offers mechanical rigidity and electrical continuity with the chassis, helping to maintain grounding and EMI shielding. A standardized form factor ensures compatibility with most ATX-style rear panels, and the included pack of five allows multiple slots to be covered during assembly or maintenance. Metal blanks are more durable than plastic alternatives and resist deformation from screw tightening and case handling.

Suitable for

• Desktop PC assembly and system builds
• System maintenance and cleaning to prevent dust entry
• Upgrades where expansion cards are not currently installed
• Enclosures requiring maintained airflow and EMI mitigation

Key specifications

• Quantity: pack of five full-height slot covers
• Material: metal (steel or comparable conductive alloy)
• Form factor: full-height expansion slot compatible with standard ATX rear panels
• Finish: protective coating to resist corrosion and wear
• Mounting: secured with standard expansion slot screw or thumbscrew (screw not included in all systems)

How to use

Align a slot blank with an empty full-height expansion opening on the rear panel of the chassis, then secure it using the case's standard expansion slot screw or thumbscrew. For multiple adjacent empty slots, install additional blanks from the pack to maintain consistent airflow and chassis continuity. Ensure the case is powered down and unplugged from mains before installing or removing slot covers to avoid contact with internal components.

Recommendations

For optimal airflow and dust protection, install slot blanks in any unused expansion positions and check that each cover is firmly fastened to provide good electrical contact with the chassis. During periodic maintenance, remove accumulated dust from the covers and surrounding vents. When planning hardware changes, keep spare slot blanks available to immediately replace removed cards and preserve chassis grounding and airflow.
