Fence Caps - Post Caps for Chain Link, Wood, and Ornamental Fences

Protect and finish your fence posts with the right fence caps. Our fence post caps collection covers chain link post caps, wood fence post caps, and ornamental iron post caps in multiple sizes to fit standard post diameters. Fence caps keep moisture out of hollow metal posts to prevent rust and rot, and provide a clean finished look at the top of every post. Chain link post caps snap onto 1-3/8, 1-5/8, and 2 inch posts. Wood post caps are available in flat and pyramid styles. Ornamental caps fit square and round decorative post tops. All caps are built from galvanized steel or durable polymer. Browse by post size or fence type to narrow down your selection quickly.

Frequently Asked Questions

What size fence post cap do I need?

Measure the outside diameter of your fence post. Common chain link post sizes are 1-3/8, 1-5/8, and 2 inch. Wood posts are typically 4x4 or 6x6. Choose a cap that matches your post outside diameter for a snug fit.

Do fence post caps prevent rust?

Yes. Fence caps cover the open top of hollow metal posts, blocking rainwater from entering and pooling inside, which is the primary cause of internal post corrosion.

Can fence caps be used on both wood and metal posts?

No. Fence caps are designed for specific post materials and sizes. Chain link caps fit round metal posts; wood caps are designed for square lumber posts. Check product descriptions for compatibility.

Are fence post caps necessary?

They are strongly recommended for hollow metal posts. An uncapped post collects water and debris inside, accelerating internal rusting that is invisible until the post is structurally compromised.

What material are fence post caps made from?

Most chain link fence post caps are made from galvanized steel or UV-resistant polymer. Ornamental fence caps are typically powder-coated steel. Wood post caps are available in metal or PVC.

How do I install a chain link fence post cap?

Chain link post caps press onto the top of the post tube and are held in place by friction. Some styles include a set screw for a more permanent installation. No special tools are required.

What is the difference between a loop cap and a post cap?

A loop cap is used on line posts (interior posts) and has a loop opening to guide the top rail through. A post cap is used on terminal posts (end, corner, gate posts) and fully covers the post top.

Can I paint fence post caps?

Galvanized steel caps can be painted with a primer designed for galvanized metal, followed by a rust-inhibiting exterior paint. Polymer caps can be painted with adhesion-promoting spray paint designed for plastic.

How long do fence post caps last?

Galvanized steel caps last many years outdoors. Polymer caps resist UV and weathering well but may become brittle in very cold climates over a decade or more. Inspect annually and replace any cracked or missing caps promptly.

Do ornamental fence post caps fit chain link posts?

Typically no. Ornamental caps are designed for square iron fence posts, while chain link caps fit round tubular posts. Always match the cap style to your specific post shape and diameter.
