AZEK Harbor Post Caps
What It Is
The Azek Harbor Post Cap is a composite post cap made from Azek-style PVC material, crafted by Nantucket Post Cap. It’s designed to slip over the top of a square deck, fence, or structural post, protecting the post from moisture and weather while giving it a finished look with a slight pyramid/pointed top for a bit of visual interest.
Materials & Durability
PVC Composite Construction
- Made of Azek-type solid polymer material — looks and feels like painted wood but won’t rot, split, twist, or warp like natural lumber.
- Impervious to moisture and insects, so it’s ideal for outdoor posts exposed to wet or humid conditions.
Paintable Surface
- Accepts paint very well, so you can customize the color to match your deck, railing, or trim.
- Painting before installation protects against dirt, mildew, and UV damage and is usually recommended to maintain the warranty.
Maintenance-Free After Painting
-
Once properly painted, the cap becomes essentially maintenance-free — no annual staining or sealing required.
Fit & Style
Harbor Profile
-
Features a slightly pointed top — a classic look that blends traditional and contemporary styles without being too ornate.
Custom-Made to Size
- Caps are made to order slightly larger than the listed size to fit snugly over your post.
- Available for a wide range of post dimensions — from smaller 3½″ posts up through larger 8″ (and likely other sizes available by request).

The following is recommended:
- AZEK doesn’t have a finish and that leaves the material subject to dirt, smudges, mold and mildew.
- Properly prepared and painted with even brush strokes gives the appearance of finely painted wood.
- A properly painted finish will last for years protecting the substrate from mold, mildew and the UV rays from the sun. AZEK surfaces must be clean, dry and void of any foreign material such as dirt, oil, grease or other contaminates that may come from normal handling, storage and/or installation prior to painting. Use a 100% acrylic latex paint with colors having a Light Reflective Value (LRV) of 55 or higher.
AZEK products WILL NOT BE COVERED UNDER WARRANTY if they are not treated prior to installation.
