Post Cap Sizing

4x4 Post Caps

Our 4x4 fence post cap is made to fit nominal sized posts (3.5" x 3.5"). Common fence posts are nominal sized but we always recommend double checking before ordering. If your post is a true 4x4, please view our True 4x4 Post Cap collection.

6x6 Post Caps

Just like our 4x4 cap, our 6x6 fence post cap is made to fit a nominal sized post (5.5" x 5.5"). We also have a True 6x6 Post Cap collection. Decorative 6x6 post toppers

4x6 Post Caps

Our 4x6 post cap is made to fit a nominal 4"x6" post (3.5"x5.5"). Unfortunately, we do not offer a true 4x6 post cap due to its odd size.

Post Toppers

Our fence post toppers are made to bolt onto the top of any type of wood post. Although they don't add as much protection as our fence post caps, they still keep some water and bugs out while adding a very decorative metal touch to your posts! Instillation is easy for these. All you need to do is place them on your post and secure them with our color matching screws.

Our metal post caps are made to fit tight so your fence post, mailbox post... will stay looking new for longer. As a result of this, some trimming of the post may be necessary. Installation Instructions are included in each package and is also on our website.

Post Cap Materials

Our steel post caps are made of solid, pressed steal, made in the USA. We also offer wrought iron "pyramid style" post caps. The wrought iron post caps are much thicker than the steel caps but not as strong.

The decorative finial is made of either steel or wrought iron (depending on the style of the post topper). The steel is 12 gauge (about the thickness of a nickel). Our wrought iron finials come in various thicknesses.

Each post cap includes color matching, stainless steel hardware to securely mount your cap to your fence post. These are a great addition to our products because it creates the most seamless and secure installation offered on the market!

We use powder coat paint to create a consistent coating on each post cap. Powder coat is a great way to weatherproof our products to make our post caps last even longer. Powder coat also looks much better then any other form of painting!

Wrought Iron Fences

We have the perfect sized post caps for wrought iron metal fences. Be careful, not all of our post caps are made to fit wrought iron fencing. Check out our True Sized Post Caps to find one to fit your metal post and fence.

Steel Fence Post

The most uncommon type of fence post, but much like the wrought iron fence. Iron metal fences are typically true-to-size so they will also need our True Sized Post Caps.
