Choosing the Right 4x4 Post Cap

One of the most common mistakes when ordering fence post caps is selecting the wrong size. Most modern "4x4" lumber actually measures about 3½" x 3½" and requires a nominal 4x4 post cap. Older posts and specialty applications may require a true 4" x 4" cap. Measure your post before ordering to ensure a proper fit.

Our copper and stainless steel post caps are commonly used on:

Fence posts
Deck railings
Gates
Pergolas
Arbors
Gazebos
Mailbox posts

Copper fence post caps develop a natural patina over time, while stainless steel provides a clean, modern appearance with excellent corrosion resistance. Both options help protect exposed wood post tops while adding a professional finished look.

We include matching copper rosehead nails with our copper post caps for installation.
