Are you ordering the correct size post cap or trim? We list the opening size of the post skirt. The size you select should measure equal to or slightly larger than your post in order to slide into place over the post. For example, a 6x6 post may actually measure 5.5" x 5.5", so you would order a 5.5" cap. Contact us if you’re unsure which size you need. The Deck Store Online has partnered with this manufacturer to have these caps and bases made for you. While most common sizes are in stock, special sizes are made to order and shipped directly from the factory. Please allow 7-10 days for this item to be produced and shipped to you. Note: These items are made to order and non-returnable. Please check your sizes carefully.
Nantucket Post Caps are sized according to the actual physical measurement of your post. All caps are made 1/8" larger on the opening than the actual post size you specify. For example, if your 4x4 standard post truly measures 3-1/2" x 3-1/2", choose that size and your cap will come with an inside measurement of 3-5/8" x 3-5/8" to allow it to slip over your post.
