If the prospect of cutting, stripping and twisting wires together is too much, consider Terex's Light Hub installation system. Featuring small but durable plugs that simply chain lighting together, this system saves time, money and the frustration of troubleshooting. The female to female adapter is a simple device that allows you to link Male/Male Light Hub extension wires (sold separately) together to create custom lengths or make the most of leftovers. For maximum flexibility these are recommended for a first time installer.
