Our extendable festoon belts come standard with a cap to protect the connector. When extending the festoon belt, this cap will need to be removed. To reuse the extendable festoon belt by itself, the cap will need to be reattached to the connector, to ensure it is waterproof. Should the cap have gone missing, then we provide these loose caps as a replacement.
Note: this is not the end cap for festoon belts.
