Dubro Heavy Duty Ball Link 4-40 RC Linkage - DUB884

The Dubro DUB884 Heavy Duty Ball Link is a 4-40 threaded linkage connector designed for use in RC aircraft control systems. Ball links are used to connect pushrods and control rods to servo arms and control horns, allowing smooth articulation of control surfaces such as ailerons, elevators, and rudders. The heavy duty construction of the DUB884 makes it a solid choice where standard ball links may flex or wear prematurely under higher loads.

• 4-40 thread size suits standard RC aircraft linkage hardware
