Southco Keylocking Flush/Knob Latch - Black Plastic

The Southco Keylocking Flush/Knob Latch in black plastic (MPN 93-303) is a precision-engineered access control mechanism designed for equipment enclosures, instrument cabinets, and tactical cases where secure closure with restricted access is required. This keylocking latch combines a push-button release with a threaded body installation for reliable one-hole mounting on panels up to 0.41 inches thick, making it a compact solution for applications demanding both functionality and security.

The latch accommodates grip ranges between 0.88 and 0.91 inches, with an optional ejector spring that helps eliminate rattling during transport or field use—a critical feature when equipment silence matters. The threaded body and nut installation method provides positive retention without requiring fastening from the rear of the panel, streamlining integration into existing or new designs. Black plastic construction keeps weight minimal at 0.2 lbs while maintaining corrosion resistance in demanding environments. The flush/knob design offers ergonomic access while maintaining a low profile suitable for compact storage solutions.

This latch is specified by equipment manufacturers, military logistics operations, and field professionals who need keyed access control on portable storage, ammunition boxes, tool kits, and secure transport containers. The combination of push-button operation with key-lock security prevents accidental opening while protecting contents from unauthorized access. For buyers sourcing OEM replacement latches or upgrading existing enclosures, the Southco 93-303 delivers verified compatibility and the durability expected from a recognized industrial fastener brand.
