Description

Maximize lighting performance and coverage with the SwitchToLED Quadruple 90° Tenon Adapter, designed to mount four LED fixtures on a single 4-inch square pole. Featuring four horizontal tenons positioned at 90-degree angles, this adapter ensures full 360° light distribution, making it ideal for large outdoor spaces such as parking lots, roadways, campuses, and industrial facilities.

Engineered to fit standard 4" x 4" square poles, this adapter converts a single pole top into a multi-directional lighting system, reducing the need for additional poles and lowering installation costs. It supports standard 2-3/8 inch OD slip fitter mounts, ensuring compatibility with most commercial LED area lights, shoebox fixtures, and flood lights.

Constructed from heavy-duty steel with a durable powder-coated finish, this adapter offers superior strength, corrosion resistance, and long-lasting outdoor performance.
