The Triple 120° Horizontal Tenon Adapter is a heavy-duty mounting accessory designed for outdoor lighting applications, particularly for attaching multiple light fixtures (such as LED floodlights or area lights) to a single pole or tenon at 120° intervals. It provides a secure, horizontally oriented three-arm configuration that allows symmetrical distribution of lighting heads around a pole.

This adapter is manufactured from high-strength 0.235″ steel (approximately 6mm thick), processed according to strict engineering drawings. It is ideal for commercial, industrial, sports, and municipal lighting projects where wide-area illumination and balanced weight distribution are required.
