Since 1988, The Nantucket Post Cap Company has been creating fine post caps, finials, arbors, gates, benches, tables, and pergolas made out of the highest grade of redwood and cedar. All their high quality Post Caps are made from the best grade of clear, all heart, vertical-grain Redwood or Clear Western Red Cedar, so you can choose the wood species that works best for your fencing, deck, or other landscaping project.

Both Red Cedar and Redwood have great resistance to moisture, decay and insect damage. These wood types also have exceptional dimensional stability. Your Post Cap will lay flat, stay straight, retain fasteners, and provide a firm base for many types of stains and paints, giving you a post cap that will hold up to the elements for years to come.

Post caps, a.k.a. fence caps, are decorative structures covering the tops of wooden posts on outdoor decks and wooden fences. Not only do they enhance the outdoor wooden structure, but they protect the top of the wooden post from cracking and splintering. Post caps will also cover up any uneven mill cuts or other eyesores on top of the fence or deck post. Available for nominal post sizes of 4x4, 5x5, 6x6, and 7x7.

This cap is a non-slip over cap meaning there is no molding underneath the post cap.  Non-slip over post caps sit on top of your existing post with no overhang.

How to choose the correct post cap size:

Nantucket Post Caps are sized according to the actual physical measurement of your post.  All non-slip over post caps are made a bit larger on the underneath then the actual post size you specify.  For example, if your 4x4 standard post truly measures 3-1/2" x 3-1/2", then you would choose that size and your cap would have the correct size overhang for your post. 

All Nantucket Post Cap products are made in the U.S.A.
