Goovilla 4x4 Post Cap Black – 24 Pack, Waterproof Deck Caps for 3.5 x 3.5 Posts

Goovilla 4x4 Post Caps Black Performance and Style for Wood Posts

Designed to cap the tops of wooden posts sized around 3.5 by 3.5 inches, these caps deliver a clean, finished look while protecting the post tops from daily exposure. The actual internal size is 3.6 by 3.6 inches, which covers most standard posts. If your post is slightly larger, light sanding can help achieve a snug fit. The frosted black surface adds a contemporary touch that blends with a variety of deck, fence, and railing styles for outdoor spaces you can imagine as a little more polished.

In everyday use, Goovilla caps feel substantial without being heavy. They are crafted from weather-ready PP plastic that stands up to sun, rain, and temperature shifts. The four way symmetry and a gentle slope on all sides promote rain runoff, which helps keep the top area drier and reduces surface wear over time. While they are not a replacement for structural maintenance, they contribute to a neat, protective finish that enhances curb appeal.

Durable construction built for outdoor life

• Four reinforced internal ribs provide added rigidity and stability.
• Weather-resistant PP plastic; resistant to rust, cracking, and UV fade for long-term color retention.
• Frosted black finish reduces glare and stays visually consistent under bright sun.
• Tapered, water-shedding design helps rain slide off the top rather than pool there.
• Protects the wood post from moisture, sun exposure, and minor abrasions while delivering a tidy profile.

Easy, two-step installation with everything you need

Installing is quick and straightforward. Place the cap on the wooden post topper and secure with screws. The package includes all necessary hardware, plus a small batch of spare screws to cover multiple posts in one session.
