These post caps are made to slip over the top of a 4x4 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. 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.
