4X6 Post Caps

American Made 4x6 Post Caps

Our 4x6 post caps are designed to protect your fence or deck posts and be attractive at the same time.  These post caps are made from a high-grade plastic resin and come with our 5 Year Guarantee. These caps fit nominal posts measuring 3.5" x 5.5" up to 3.75" up to 5.75". They are made of the same UV stable resin as the other post caps in our SNAP-Cap line.  We use the material to create a line of fence post caps that we believe are superior to comparable wood products in every way. The material gives our caps an incredible weather-ability while being surprisingly light weight.

Built for projects where durability and clean design go hand in hand, our 4x6 fence post caps offer a reliable way to shield exposed wood while elevating the overall appearance of your structure. These caps are engineered to handle moisture, temperature swings, and direct sunlight without losing their shape or finish. Contractors and homeowners alike choose 4x6 post caps for their consistent fit and long-term performance. The result is a polished, low-maintenance solution that keeps your outdoor spaces looking sharp year-round.
