Copper Fence Post Caps

Copper Fence Post Caps

Long-Lasting Protection for Wood Fence Posts

Wood fence posts fail where you can’t see it first—at the top. The exposed end grain pulls in water, leading to internal rot, splitting, and early replacement. Our copper fence post caps are designed to stop that problem at the source by covering and protecting the most vulnerable part of your post.

Made from heavy-duty 21-gauge real copper, these caps are thicker than most hardware store options and built for long-term outdoor use. The angled design helps shed water away from the post, while the copper naturally resists corrosion and develops a rich patina over time. Available in multiple sizes including 4x4, 4x6, 6x6, and 8x8, these caps provide both protection and a clean, finished look.

Do fence post caps prevent rot?
Yes. They block water from entering exposed wood grain.

What size cap do I need?
Be sure to measure your post because size names don't always match the true size. For example, a 4x4 post could be between 3 1/2 inches and 4 inches.

A 3 1/2" post requires a "nominal 4x4" fence post cap, but
a 4" post requires a "full 4x4" fence post cap.

Are metal caps better than wood?
Yes. Metal caps last much longer and won’t absorb water.
