If the prospect of cutting, stripping and twisting wires together is too much, consider Trex's LightHub installation system. Featuring small but durable plugs that simply chain lighting together, this system saves time, money and the frustration of troubleshooting. The 3-way splitter is the backbone of the system. It has 3 ports that connect your power source to your lights. Simply link these together with Male/Male LightHub wires (sold separately) and your next Trex Outdoor lighting install will be faster and easier.
