Tenon Adaptor

A four horizontal tenon adapter lets you mount up to four outdoor LED fixtures from a single pole or support. Each tenon sticks out at a right angle, creating four mounting positions so you can illuminate large areas from one central point. This makes it ideal when you need wide, even light distribution in open spaces.

As the name suggests, this adapter supports up to four LED fixtures — one on each tenon. Each tenon provides a place to attach a light with a standard slip-fitter or tenon mount, allowing you to light four directions from one pole. This reduces the number of poles you need and helps fill large areas without gaps.

The tenons are set at 90-degree intervals so that each fixture points in a different direction — typically north, south, east, and west. This arrangement spreads light evenly across a large area and eliminates dark spots that can occur when lights are clustered in one direction.

Yes. With the proper pole mount base, this adapter can be used on both square and round poles. For square poles you would use a square-to-round adapter, and for round poles you mount it directly. This flexibility helps it fit existing infrastructure without costly pole changes.

Primarily, this adapter is intended for pole mounting where multiple lights need to spread out over a large footprint. In some cases, with the right bracket or arm, a four-tenon adapter can be adapted to wall or structure mounts, but it is most commonly used on poles because of the multi-direction light spread it provides.

Four-tenon adapters are often used in parking lots, sports arenas, campuses, industrial yards, large intersections, airports, and other wide, open spaces where a single pole with multiple lights can deliver broad and uniform coverage. They reduce pole clutter and make it easier to light large areas efficiently.
