Four light spoke adapters @ 90 are available for the new LED fixtures that are being mounted on new or old parking lot lighting poles.These adapters allow you to upgrade from one light per pole to four fully adjustable lights per pole at 90 degrees maximizing your light output without adding a new light pole. Using the four light at 90 degree mount allows you to use larger fixtures and have light coverage in a 360 degree span around your pole. Made to fit over any existing 2-3/8 light pole tenon, making installation a snap. Spoke adapter arms are available in standard lengths including 8", 10" and 12". Each arm is made to accept a standard slip fitter or cobra head style installation.
