These post caps are made to slip over the top of a 4"x4" fence or deck post for a decorative finishing touch or to hide irregular post ends. These post caps can be attached by either applying exterior caulk to the under-side of the post cap, or by nailing the post cap to the post with finish nails. As with any exterior product, it is recommended to apply a good quality finish to preserve the wood"s natural beauty and protect the post cap. The copper has been coated to ensure it is in best possible condition during installation. When exposed to outdoor elements, copper will weather to a natural patina.CAPITOL CITY LUMBER has a full line of post caps and tops for decks, fences and outdoor structures.**** Please contact us at 1-800-244-6492 with any questions on this product or other products on our website.**** RETURN POLICY: If for any reason you are not completely satisfied, please return this product within 30 days of receiving and we will give you full merchandise credit back.
