Du-Bro 4-40 Safety Lock Kwik-Link (12 Pack)

4-40 Safety Lock Kwik-Link (12 Pack) from Du-Bro - DUB818

The DU-BRO Safety Lock Kwik-Link is a dependable, easy-to-use connector designed to keep your RC control linkages secure during every flight, drive, or run. This clever design combines a standard Kwik-Link with a built-in safety lock that prevents the link from accidentally popping off your control horn—something every RC hobbyist wants to avoid. Whether you fly airplanes, operate drones, run RC cars, or enjoy boating, the Safety Lock Kwik-Link adds peace of mind to your control system.

Made from high-quality materials, this Kwik-Link provides a tight, smooth connection that stays secure even under heavy vibration or high-stress maneuvers. The safety lock snaps firmly into place and ensures the link remains attached, making it ideal for glow, gas, and electric-powered models. The connector installs easily and works with a wide range of pushrods and control horns, making it a versatile choice for both new builds and repairs.

RC pilots and drivers appreciate how this link reduces slop in the control system while keeping control surfaces—such as elevators, rudders, throttle arms, or steering—working smoothly and accurately. It’s also a great upgrade for older models that still use basic connectors without safety retention. Whether you’re building a new model or improving the reliability of an existing one, the DU-BRO Safety Lock Kwik-Link gives your RC setup an extra layer of security. It’s durable, easy to use, and offers the trusted quality DU-BRO has provided to hobbyists for decades.

• Includes a slide-lock track to prevent accidental pop-offs
