Goovilla 4x4 Post Caps Black – 4 Pack Aluminum Fence Post Caps with 8 Screws

Goovilla 4x4 Post Caps in Black bring a clean, finished look to outdoor wood posts while offering practical protection. With an actual internal size of 3.66 x 3.66 inches, these caps fit posts from 3.5 x 3.5 inches up to 3.66 x 3.66 inches. The fade-resistant coating helps maintain surface appeal, while the solid aluminum construction resists weathering, making them suitable for decks, fences, handrails, and porch supports. The wrap-around design creates a neat silhouette and helps keep moisture at bay. While precise measurement is important—some posts may benefit from light sanding if they run slightly larger—these caps are designed for straightforward DIY installation and long-term performance.
