Product Description：

The Choierlight 4" Round Pole Tenon Adapter is a heavy-duty mounting solution designed to install LED parking lot lights, shoebox lights, street lights and outdoor area lights on a 4-inch round light pole.

This pole mounting adapter provides a standard 2-3/8" O.D. vertical tenon, making it compatible with many commercial outdoor LED fixtures equipped with a 2-3/8" slip fitter mount.

Designed for new installations and LED lighting retrofit projects, the adapter provides a simple way to convert a 4" round pole top into a 2-3/8" mounting tenon without replacing the existing light pole.

Constructed from heavy-duty galvanized steel and available in Dark Bronze or Black, this commercial light pole adapter is suitable for parking lots, roadways, commercial properties, industrial facilities and other outdoor area lighting applications.
