4x4 Post Caps

Also Available On:

Protect your fence posts and add a touch of style to your outdoor spaces with these stunning, American-made 4x4 Post Caps. Our fence post caps are made from premium, long-lasting materials, offering you a 10-year quality guarantee.

Affordable Visual Appeal

A set of 4x4 post caps could be exactly what you need to level up your home’s outdoor decor. The posts of a typical wooden garden fence can seem so drab, but wooden post caps can cost you a small fortune. With our plastic-based post caps, you get the same visual effect for a fraction of the price.

Whether you choose a flat or pyramid top, consider us as a cheap, easy way to increase your curbside appeal and value.

Protect Your Fence

Along with being a gorgeous visual addition to your garden, patio, or porch, our fence and deck post caps will offer protection for your wooden posts. Water damage can decimate wooden fences and be extremely expensive to repair, but with solid post caps sealing the top of your posts, damaging levels of seepage will be a thing of the past.

Protection and style all in one! 

ASA Resin

We make our own 4x4 post caps right here in the US from ASA resin, a sturdy plastic used in the automotive industry that won’t fade, expand, crack, or degrade like wood does over time. This weather-resistant material is ideal for sealing up your fence posts, requiring no maintenance within at least 10 years.

ASA resin is also UV resistant, chemical-resistant, and thermally stable.

Unique Easy Installation

Our patented fast installation method makes fixing these post caps a breeze. Just choose the size for you, with nominal sizes fitting 3.5”x3.5” posts and actual sizes fitting 4”x4”, screw in your base, and snap your top into place. The method is quick, easy, and will hide the screws effectively.

Our Full Range

Beyond our flagship ASA resin post caps we also offer aluminum, PVC, and 4x4 solar post caps, any of which you can use to add a stylish dimension to your garden, patio, or deck fence posts.

Note: Our aluminum post caps aren’t made in the USA and don’t feature our label of quality - we offer them with a one-year warranty.
