Alternate Finger Slot Mount Fingerstock Gasket
Alternate Finger Slot Mount Fingerstock Gaskets provide effective EMI/RFI shielding, grounding, and electrical contact for electronic enclosures, cabinets, and chassis assemblies. Designed to clip into slots or slide onto mounting tracks, these beryllium copper fingerstock gaskets offer secure installation and long-term performance.
The alternating finger design delivers reliable spring contact while maintaining consistent electrical continuity across enclosure seams. In shorter lengths, these gaskets are commonly used as ESD contacts, while longer lengths provide high-performance EMI shielding for access panels and removable covers.
Manufactured from high-strength beryllium copper, Alternate Finger Slot Mount gaskets offer excellent conductivity, corrosion resistance, and durability in demanding commercial, industrial, aerospace, and telecommunications applications.
Leader Tech offers a variety of sizes, plating options, and custom configurations to meet specific EMI shielding and grounding requirements.
