Dubro Kwik Link Safety Lock 4-40 RC Linkage - DUB817

The Dubro DUB817 Kwik Link Safety Lock is a 4-40 threaded pushrod connector designed for use in RC aircraft control linkage systems. Sold in a pack of two, these connectors allow servo pushrods to be connected and disconnected quickly without tools, while the safety lock mechanism prevents the link from vibrating loose during flight. Dubro is a long-established name in RC linkage hardware, and the Kwik Link range is widely used across fixed-wing aircraft builds and repairs.
