Bring your deck to life with the clean, minimalist look of the Standard Post Cap for TimberTech Classic Composite Railing. These durable, low-maintenance composite caps will hold their color and appearance for years to come.

How To Choose Your Post Cap Look

Each size of TimberTech Standard Post Cap has its own unique look:
  • The 4-1/4-inch x 4-1/4-inch post cap is a thicker, more rounded-off profile
  • The 5-inch x 5-inch post cap is a wider, flatter look
  • The 5-1/2-inch x 5-1/2-inch post cap is rounded on the edges with a more pronounced pyramid at the top

For a larger, more substantial post cap (for 5-1/2-inch post sleeves only), you can check out the Island Post Cap style here.

How to choose the right size

Check out our Post Cap Diagram. Choose a post cap with an opening size slightly larger than your posts or post sleeves.
