Similar to the brake cable on a bicycle, these cables exert pulling force so you can control components such as latches, release valves, and brakes. When you relax your pull, springs in your component pull the cable back. To connect these cables, anchor them on both ends through a panel or bulkhead using the included nuts. They have a steel core, but they’re flexible so you can weave them around obstacles and corners to connect to hard-to-reach components. Surrounding the cable is a plastic cover that stays in place as the cable slides through smoothly. The cover is durable and protects the cable from dirt and abrasion.

Once they’re connected, control these cables using a knob or handle. Some come with a knob attached, but add your own otherwise.
