EN-Labs 11-001-347 PCI Slot Covers 5pcs Black Mesh Steel 4.75in

Five-piece full-profile PCI slot covers

This set supplies five black mesh steel brackets that seal standard full-profile expansion openings in ATX and micro-ATX chassis. Each plate measures 4.75 inches by 0.75 inches and ships with mounting screws for immediate installation. The metal construction adds rigidity while the open mesh pattern permits airflow through unused slots.

Mesh design balances dust filtering and airflow

The vented hollow-out pattern lets ambient air enter the case while blocking a portion of incoming dust, helping internal components stay cleaner. Because the mesh is not a fine filter, very small particles can still pass, so builders who need stricter dust exclusion should add dedicated intake filters elsewhere in the case.

Tool-free fit for standard rear brackets

The covers align with the 120.6 mm by 19.1 mm cut-outs found on most full-profile cases and secure with the included screws. They require no motherboard header, power connection or software, leaving all expansion lanes and drive bays untouched. Low-profile or half-height slots cannot accept these plates.
