Dubro Kwiklink Spring Steel 4-40 RC Linkage - DUB601

The Dubro 601 Kwiklink Spring Steel 4-40 connectors are a pack of 12 threaded pushrod connectors designed for securing control linkages in RC aircraft. Known as DUB601, these spring steel Kwiklinks provide a reliable mechanical connection between pushrods and servo horns or control horns, using the standard 4-40 thread size widely used across fixed-wing RC models. The spring-steel construction holds the link securely in place while still allowing quick adjustment or removal without tools, making them a practical choice for building or maintaining RC aircraft linkage systems.
