Wooden Post Caps for Fence and Deck

• Protect your 4x4 (3 5/8”) fence posts with our black plastic post caps. Most 4x4 fence posts are actually 3 1/2 inches by 3 1/2 inches, but once planed, each side measures around 3 5/8 inches.
• Our post caps are crafted from high-quality and durable plastic, designed to withstand extreme weather conditions. They are thick, weatherproof, UV-resistant, heat-resistant, impact-resistant, and waterproof.
• Wooden fence posts can last for many years, but exposed end grains are a weakness. Moisture seeping into the end grain can shorten the lifespan of the posts significantly.
• Specifically tailored for an inside dimension of 4" x 4", our matte black pyramid caps are ideal for wooden posts with dimensions of 4" x 4". They are not suitable for other post sizes.
• Understand post cap sizes with our guide. The listed measurement on the cap corresponds to the size of the rough lumber or undressed post it fits. For example, a 4" x 4" rough lumber post matches a cap designed for a post measuring 4" x 4".
