We are a Veteran owned family business in Madison, IN and truly appreciate our customers!  Please read the following if you have any questions, please do not hesitate to contact us.   Our post caps come in a variety of sizes so please check your post size before ordering.    4x4 nominal Post caps for 3-1/2" posts - These are the most common size pressure treated deck post that are sold in lumberyards and are commonly called 4x4 post.  True 4x4 post caps (actual 4" size) - Some hardwood post and even some pressure treated post measure anywhere between 3-5/8" and 4".  In these situations, you should order a true 4x4 post cap.  These also, typically fit 4" metal posts with rounded corners True 5x5 post cap - These actually measure 5" underneath and are commonly used for plastic post or post sleeves or undersized wood posts - Note: that we have rounded edges on our post caps so, if the plastic post has really square edges these probably will not work. 6x6 nominal post cap for 5-1/2" posts - 5-1/2" posts are the common size pressure treated deck posts that are sold in lumberyards and are commonly called 6x6 post even though they are actually 5-1/2" True 6x6 post caps (actual 6" size) - Some hardwood post and even some pressure treated post measure anywhere between 5-5/8" and 6".  In these situations, you should order a true 6x6 post cap.  Also, these typically fit over metal post with rounded corners. Nominal 4x6 Post caps for 3-1/2"x5-1/2" posts - These are for pressure treated 4x6 post that are commonly found in lumberyards - these actually measure 3-1/2x5-1/2".  Please not that our post caps are true to size so if the post is a little over, they may need to dry or be sanded down somewhat for the post cap to fit properly.  Our post caps are made to fit tight to help bind the post from splitting unlike others that do not. We believe post caps should serve a purpose to help preserve your post not just for decoration. If you want to understand this more, please see our post cap installation video for more details under the "installation" tab on our website.  Finial Size for 4x4, True 4x4 and 4x6 post caps are the same. Finials for 5x5, 6x6, and true 6x6 post caps are the same.   ADDITIONAL DETAILS: Our post caps are powder coated in a large variety of colors for long outdoor life in a high-quality powder coat with UV inhibitors to resist fading in the sun and are typically fine for most locations.  If you live in coastal areas that have a "salty" environment, or these will be in high traffic areas, we suggest adding the zinc option. What is the zinc option? - our zinc option is an additional process where we put a thick zinc powder coat base layer primer before we put the final coat on.  This will ensure your post caps last an extremely long time under bad conditions. But this expense isn't necessary for most locations which is why we offer it as an add on.   Our post caps are made to fit tight and have rounded corners so as to limit sharp edges so this should be taken into account when ordering. We pre-drill holes on two sides and provide matching powder coated screws for a very finished touch. Our post caps are made from tough thick gauge steel and are much more robust and heavy duty than most other post caps you will find so you know when you order ours you are making an investment not just ordering a cheap cap that will do.  We make each post cap to order, with your particular finial, and the size you request in the finish you request.  - This is a lot of variation to offer, which is why we do not offer returns or exchanges on most products as they are in fact customized to your order.  So, please check your measurements and ask questions if needed.  Our pictures offer an accurate depiction of the size as well as the size of the finial is listed on each listing.  If you are buying several different finial types, make sure you understand the sizes as we do not coordinate the sizes of the finial with the others.  Example - if you purchase a duck and a blue herring and a raven post cap, they will be different scales. Please take this into consideration.  We can make custom sized finials if requested, but it will be a custom order, and additional fees will apply.
