Description
[SIZE CHECK: ACTUAL 4x4 ONLY] STOP and measure your post. These caps fit ONLY hollow vinyl posts with an actual 4" x 4" outer diameter. They will NOT fit standard 3.5" x 3.5" wood posts. Avoid returns by confirming your post type before ordering.
[WEATHER-SHIELD PROTECTION] Crafted from durable, fence-grade vinyl that acts as a tough barrier against rain, snow, and debris. These caps prevent water from accumulating inside hollow posts, protecting your fence or deck system from internal damage.
[CLASSIC PYRAMID STYLE] Instantly upgrade your curb appeal. The sleek, low-profile pyramid design (1.77" high) adds a clean, finished look to decks, porches, and mailboxes. It's the perfect professional touch for any residential project.
[SECURE SLIDE-OVER FIT] Features a 7/8" deep skirt for stability. Installation is a breeze—simply slide the cap over the post. For permanent hold in high-wind areas, we recommend a small bead of clear outdoor silicone (sold separately).
[2-YEAR WARRANTY BACKED] Designed for reliable outdoor performance. These sturdy PVC caps protect your posts from cracking and environmental wear. Backed by a 2-Year Warranty for your peace of mind.
Professional Physical Protection for Your Vinyl Fencing System
Leaving your vinyl posts open exposes them to rain collection and debris buildup, which can compromise your fence's stability. Our RECTOO 4x4 Vinyl Post Caps provide a precise seal with a classic, low-profile pyramid design. It is the essential final detail that turns a standard fence installation into a polished, finished look.
Q: Will these caps fit standard 4x4 wooden posts?
A: NO. This is a common sizing mistake. Standard 4x4 wood posts measure 3.5" x 3.5". These caps are precision-molded to fit True 4.00" x 4.00" hollow vinyl sleeves or posts only. Please measure the outside diameter of your post before ordering.
Q: How do these caps protect my outdoor fence?
A: By sealing the top of the hollow post, these caps act as a waterproof barrier that prevents rain and snow from entering the interior. This physical protection helps prevent water accumulation and internal post degradation over time.
Q: What is the best way to install them?
A: These are slide-over external sleeve caps. They feature a 7/8" (0.875") deep skirt for a stable fit. For permanent security in high-wind areas, we recommend applying a small amount of clear outdoor silicone (not included) to the inner rim before sliding them on.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for RECTOO products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
