The Outdoor Post Adapter takes the headache out of mounting a post light when the shapes don’t match. Made from aluminum and built for exterior exposure, it bridges a 2.5" square fixture mount to a 3" round post with a clean, industrial feel. Use it on a front porch or along a garden pathway when you want a secure, straightforward install. Hubbardton Forge also offers Marine Grade Black and Marine Grade White — AAMA 2605-rated finishes with a 10-year coastal warranty and lifetime warranty in non-coastal locations, for the highest level of protection against salt air and weather.
