The Connector is used to convert the single lead cable from the power pack in to two outlets. This is a great way to run two separate light strings from the just the one plug. For example: If you wish to put lights on two separate trees that are close together but only have one mains outlet. Simply run the lead cable from the power pack to the base of the trees & attach the connector. This will now give you two outlets, one for each tree. This accessory is 30cm long each end & can be connected together to create a more advanced display. Each section of the connector measures 15cm.
