Post Caps

The Deck Store is the proud supplier of all the major brands of Post Caps for your deck rail or fence project. Post Caps are designed to be both decorative and functional. The typical design diverts water and snow from causing the end grains of your posts to split and decay.

Post Caps come in almost every imaginable color, shape and material. Further complicating the selection process is the enormous number of sizes available and the way the sizes are described. We try to make this as clear as possible so you get the cap you expected the first time. Terms like "Actual" and "Nominal" are used frequently. Much like a 2x4 is actually 3-1/2" x 1-1/2" in size, post cap manufacturers do the same thing, but to mix it up some manufacturers of Composite or PVC post sleeves only use actual sizes in their description. As a general rule if you select a post cap from the same manufacturer as the post sleeve you're likely going to get the proper cap. Manufacturers want you to use their products so they might change the shape slightly (Rounding or projecting corners) so only their caps will fit. If you have a question about a particular cap Contact Us and we will do our best to help you. Sending a digital picture with measurements helps too.
