Post Caps for Round and Square Fence Posts
A fence is only as strong as its weakest point, and often, that’s the top of the post. At Fenceweb, we offer a wide selection of durable fence post caps that protect your posts from water, rust, and impact damage, while giving your fence a professional finish. Fenceweb is the leading supplier of fence accessories in the United States.
Reliable Protection for Every Post Type
Whether you’re working with round posts or square profiles, we have caps to match. Our range includes sizes to fit 1 3/8", 1 5/8", 2", 2 3/8", 2 1/2", and 3" posts. The right cap keeps rain and dirt out, extending the life of your posts and minimizing maintenance.
