A deck can be the center piece of your home's outdoor space. Our 4x4 post caps will add a decorative element that enhances the architectural appeal of your home and the landscape. These cedar color flat top 4x4 post caps are made of ASA resin. It is a hard plastic that is known for its strength and durability. It is also UV and impact resistant. We chose to name this post cap cedar color as a way of distinguishing its redder hue from brown, which is a darker shade of brown. All of our caps will work for either a fence or deck, but we feel that the flat top is an excellent solution for outdoor entertaining and works exceptionally well on deck posts and railings.

ASA resin requires no maintenance, and that will never be the case with wood post caps. And one of the greatest benefits of our plastic post caps is that we’re selling you a superior product line for a fraction of the cost of comparable wood fence post caps. And they’ll last far longer, too.
