TonGass (24-Pack, Black) 4"x4" (3 5/8") Wood Fence Post Caps - Wooden Fence Cover Deck Post Cap, Durable Plastic Water-Proof and UV-Proof, Protect Wooden Poles from Cracking and Rotting

BLACK PLASTIC POST CAPS FOR 4X4 (3 5/8”) FENCE POSTS - Most 4x4 fence posts actually have nominal dimensions of 3 1/2 inches by 3 1/2 inches. Once planed, each side would be around 3 5/8 inches. With inside dimensions of 3 5/8 inches by 3 5/8 inches and an edge height of 1/2 inch, these black plastic fence post caps will fit perfectly on most fence posts.
MADE FROM HIGH-QUALITY AND DURABLE PLASTIC - Fence post plastic caps need to withstand extreme changes in weather. Made from thick, highly durable, and weatherproof plastic, our plastic post caps are UV and heat-resistant, impact-resistant, and waterproof. There won’t be fading, cracking for years to come!
PROTECT WOODEN FENCE POSTS IN A STYLISH WAY - Pressure-treated wood can last for many years, but wooden fence posts have one weakness: exposed end grains. Moisture seeping into the end grain can easily half the posts’ lifespan. And the best part? These plastic post caps don’t look tacky. With their sleek and timeless appeal, these fence post caps will definitely add a stylish touch to your home’s exterior.
EASY TO INSTALL AND SECURE FENCE POST CAPS - The black caps will slip easily on top of the posts. Even when the post is a few millimeters bigger, the caps will flex enough to fit, but it won’t stretch further. There are 3 options in securing the caps to the posts: nails, screws, and adhesive. For both nails and screws, you’ll need to drill a pilot hole in at least two sides of the caps. If using an adhesive, ensure that said adhesive will bond on both plastic and wood.
8 MORE FENCE POST CAPS FOR THE SAME PRICE - This is probably the most affordable pack of fence post plastic caps in the market! For the same price as 16-pack fence post caps, you have 24 plastic caps you can use both on your fence and deck posts!
