When adding four lights to your existing light poles but need the orientation to be at 90 degrees, the four light square x-configuration is best way to get this done. With a female 2-3/8 receptacle inside the square tubing at the bottom, it fits perfectly over the standard pole top tenons that usually are furnished with todays light poles. The tenons on top of the bull horn are also 2-3/8 that will receive the standard style slip fitter on almost all standard light fixtures. This setup works well for all parking lot projects where the pole is placed in the interior of the lot. By doing it this way you can cover more of your parking lot projects without worring about adding new poles.
