This wrap is used to prevent servo wires from getting chaffed by metal and carbon fiber parts such as frame, braces, ect. To install: 1. Cut wrap slightly shorter than the servo lead you would like to install it on. 2. Slide wrap over the lead. 3. Cut 2 pieces of shrink tubing about 3/4" long 4. Slide shrink tubing over the on both ends of the wrap 5. With the shrink tubing half on the wrap and half on the servo lead carefully shrink it with a heat gun or hair dryer. When it is done it should look like it does in picture 3 Each kit is includes enough to do about 10 servos. Note: For use with Futaba connectors the shrink wrap will have to be stretched a little bit with a pair of needle nose pliers to get it to fit over the safety tab.
