Product Description：

The Choierlight 4" to 3" Round Tenon Adapter is designed to convert a standard 4-inch round light pole top to a 3-inch tenon, providing a secure mounting solution for compatible LED post top lights and outdoor lighting fixtures.

This heavy-duty pole top reducer adapter is ideal for commercial outdoor lighting projects where the existing 4-inch round pole is larger than the mounting connection required by the fixture. Instead of replacing the entire light pole, this adapter provides a practical way to transition from a 4" round pole to a 3" mounting tenon.

Available in dark bronze and black finishes, the adapter is suitable for parking lots, pathways, streets, commercial properties, parks, campuses and other outdoor post top lighting applications.

Key Features:

Converts a 4" Round Pole to a 3" Tenon

This 4 inch to 3 inch pole reducer is specifically designed for installations that require a smaller mounting connection at the top of an existing round light pole.

The adapter mounts onto a 4-inch round pole and provides a 3-inch tenon for compatible outdoor lighting fixtures.

It is a convenient solution for LED lighting retrofit projects where the existing pole and new fixture use different mounting sizes.

Designed for LED Post Top Light Fixtures

The round tenon adapter is designed primarily for mounting compatible LED post top light fixtures onto existing outdoor light poles.

Typical applications include:

• LED Post Top Lights
• Commercial Outdoor Lights
• Parking Lot Lighting
• Pathway Lighting
• Park Lighting
• Campus Lighting
• Street & Roadway Lighting
• Outdoor Area Lighting

Always verify your existing pole diameter and fixture mounting dimensions before ordering.

Heavy-Duty Galvanized Steel Construction

Constructed from heavy-duty galvanized steel, this 4" to 3" round tenon adapter is built for commercial outdoor lighting installations. The durable metal construction provides a secure mounting connection for compatible LED post top fixtures and outdoor lighting applications.

Available in Dark Bronze and Black finishes to coordinate with common outdoor light poles and post top fixtures.

Easy Retrofit Solution for Existing Light Poles

Replacing an entire outdoor light pole simply because the new fixture requires a different mounting size can add unnecessary labor and project cost.

This round pole reducer adapter provides a straightforward transition between a 4-inch round pole and 3-inch tenon, making it particularly useful for retrofit and replacement lighting projects.

The adapter attaches to the existing pole and is secured with the appropriate mounting hardware.
