Add a touch of style and class to your home’s border with one or more of these 4x4 post caps.

This product is made in a classic Black Pyramid New England manner right here in the US. With our patented design, it’s easy to install and comes at a fraction of the price of traditional wood caps, while also lasting longer on display.

These fence post caps are made from ASA resin, meaning that they will maintain their quality for a very long time without deforming due to changes in atmosphere and moisture.
