4X4 Post Caps │ White Newell Flat Top

Add a touch of regality to your standard garden fence with this 4x4 flat top post cap.

Made in a stunning white style, these caps will bring a lasting sense of class to your home borders. More reliable, cheaper, and less likely to sustain damage than wood, this product is an obvious choice for a home makeover on a budget. 

We make our fence post caps right here in the US, with this range being made from ASA resin, a strong plastic that doesn’t deform even under environmental pressure.

Enjoy your elevated borders with our post caps! Available in both nominal and actual sizes.
