Sullivan SUL550 Steel Pushrod Connector H.D.

The Sullivan SUL550 Heavy Duty Steel Pushrod Connector connects 2-56 or 4-40 threaded rods to servo arms, bellcranks, and other RC control surfaces. The exclusive brass locking tab can be bent to lock the set screw in place, preventing loosening from vibration during flight. The bellcrank attachment uses a steel nut instead of a plastic washer for added strength and durability.
