Dubro 4-40 x 5/8in Swivel Ball Links for 4-40 Rods RC Aircraft Part - DUB2160

The Dubro 2160 swivel ball links are 4-40 threaded linkage connectors designed for use with 4-40 rods in RC aircraft control systems. Sold as a pack of two, these links allow the rod end to pivot freely in multiple directions, reducing binding in pushrods and control linkages. The DUB2160 is the hardware-free version, meaning no additional ball stud or screw is included in the pack.
