The UpgradeToLED Double Tenon Adapter for 4-Inch Square Poles (Model 4C2H3) is a commercial-grade mounting solution designed to support two LED lighting fixtures on a 4-inch square steel or aluminum light pole. Featuring dual 2-3/8-inch outside diameter (O.D.) horizontal tenons, this adapter is compatible with most slip-fitter mounted LED parking lot lights, shoebox fixtures, street lights, flood lights, and area lights.
Manufactured from heavy-duty structural steel with a durable dark bronze powder-coated finish, this pole-top adapter provides exceptional resistance to corrosion, rust, UV exposure, and harsh weather conditions. Its precision-engineered construction ensures long-term durability for both new installations and retrofit lighting projects.
Ideal for parking lots, roadways, business parks, shopping centers, industrial facilities, schools, warehouses, and municipal lighting systems, the UpgradeToLED Double Tenon Adapter maximizes lighting coverage while reducing installation costs by allowing two fixtures to be mounted on a single pole.
