Dubro Dual Swivel Ball Links 2-56 RC Linkage - DUB901

The Dubro 901 Dual Swivel Ball Links (DUB901) are 2-56 threaded control linkage connectors designed for use in RC aircraft control systems. Ball links allow the pushrod or clevis to pivot freely at the control horn or servo arm, reducing binding in the linkage and keeping control surface movement smooth throughout its travel range. The 2-56 thread size is one of the most common standards in small to medium RC aircraft, making these a practical stock item for builders and modellers working on new builds or replacing worn linkage hardware.
