Dubro 4-40 Rigging Couplers RC Aircraft Accessory - DUB618

The Dubro 4-40 Rigging Couplers (DUB618) are threaded control linkage hardware designed for connecting pushrods and control rods in RC aircraft builds and repairs. Dubro is a long-established name in RC hardware, and these 4-40 couplers are a standard choice for builders working with 4-40 threaded rod on fixed-wing RC planes. Each coupler allows a secure, adjustable connection point in a control linkage system, making them useful during both initial builds and ongoing setup adjustments.
