What It Is

Material & Durability
PVC-Based Azek-Style Construction
- Made of solid polymer (PVC) composite that looks and feels like painted wood but won’t rot, deteriorate, split, twist, or warp like natural wood.
- Impervious to moisture, insects, and outdoor elements, making it ideal for climates with rain, humidity, or sun exposure.
- Accepts paint easily, so you can customize the finish to match railings, trim, or deck colors.
Note: Azek post caps are recommended to be painted before installation so that they remain protected from dirt, mildew, UV exposure, and to maintain warranty coverage.
Style & Design
Great Point Profile
- The Great Point style typically has a flat square top with double-routed bottom trim — a classic, refined look that suits traditional and contemporary outdoor styles alike.
- Compared with simple flat caps, the Great Point profile adds a subtle decorative detail without being overly ornate.
Fit & Sizing
- These caps are custom-made and are generally slightly larger than the listed size so they slip on snugly over your post.
- Available in a range of post sizes (e.g., 3½″, 4″, 5″, 6″, etc.) — you’ll need to measure the actual top dimensions of your post (not the nominal lumber size) to select the correct cap.
