4 Inch Round Pole Tenon Adapter | 2 3/8 Inch Tenon | Bronze

Product Overview

This 4 inch round pole tenon adapter provides a 2 3/8 inch tenon for mounting compatible lighting fixtures to 4 inch round poles. The adapter is finished in bronze to match common pole and fixture color schemes used in commercial and industrial exterior lighting installations.

The 2 3/8 inch tenon size is a standard slip fitter dimension, allowing this adapter to serve as the interface between the pole top and fixtures designed for that tenon diameter.

Where This Product Fits Best

This adapter is intended for installations where a 4 inch round pole is in place and the selected fixture requires a 2 3/8 inch tenon for mounting. It bridges the gap between pole diameter and fixture mounting interface, which is a common requirement when retrofitting existing poles with new fixtures or when pole and fixture specifications do not align directly.

The bronze finish is appropriate for projects where visual consistency with bronze-finished poles or fixtures is required. Exterior site lighting, parking areas, pathways, and building perimeters are typical environments where this adapter would be installed.

Performance and Functional Considerations

The adapter accepts a 4 inch round pole and presents a 2 3/8 inch tenon. Fixture compatibility depends on the slip fitter or tenon receiver size specified by the fixture manufacturer. Confirm that the fixture being mounted accepts a 2 3/8 inch tenon before specifying this adapter.

This is a structural mounting component. It does not include electrical pass-through features or wiring provisions beyond what the pole and fixture independently provide.

Installation and Long-Term Use

Installation involves securing the adapter to the top of a 4 inch round pole, then mounting the fixture to the 2 3/8 inch tenon using the fixture''s slip fitter or tenon mount hardware. Standard hand tools are typically sufficient for installation.

Once installed, the adapter requires no adjustment or maintenance under normal conditions. Long-term reliability depends on proper torque at installation and compatibility between the adapter, pole, and fixture.

How This Fixture Is Commonly Used

Facility operators use this adapter when replacing or upgrading pole-mounted fixtures and the new fixture requires a 2 3/8 inch tenon that the existing pole does not directly provide. It allows continued use of existing 4 inch round poles without replacement.

The bronze finish is selected when matching existing site hardware or when project specifications call for a uniform color across poles, adapters, and fixtures.
