RECTOO 4x4 Vinyl Post Caps White – 8 Pack, Pyramid Top, Weatherproof PVC (Actual 4.00 in Internal)

Overview

RECTOO 4x4 vinyl post caps in white offer a clean, finished look for hollow posts on fences, decks, and mailboxes. They are designed for actual 4.00 in outer diameter posts and are not compatible with standard wood posts. Before you order, take a moment to confirm your post type to avoid returns.

In pure white, the caps stay bright through seasons, and the rugged PVC formulation stands up to sun, rain, and temperature swings without warping. The pyramid silhouette complements modern, low profile fencing and mailbox accents, giving outdoor areas a polished, professional feel.

Weatherproof protection

Made from durable fence grade vinyl, these caps act as a protective barrier against rain, snow, and debris. They shield the hollow post interior from moisture, which can help minimize interior wear and staining over time.

Design and fit

The classic pyramid style features a low profile that adds a subtle upgrade to outdoor spaces. At 1.77 in tall, the cap delivers a polished finish without appearing bulky.

• Weatherproof PVC material
• 7/8 in deep skirt for a stable, slide-on fit

Easy installation and use cases

With a simple slide-on design, these caps refresh posts along fences, decks, and mailboxes. They offer a neat, professional finish and can help protect against water intrusion in exposed outdoor settings. Ideal for quick upgrades during seasonal maintenance. You will notice a clean snap as the cap seats over the post, creating a crisp line along your features.

• Fit only hollow posts that are true 4x4 at the outer dimensions
• Not intended for wood posts
• For high wind locations, a small bead of clear outdoor silicone can improve hold
