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 since 1988. 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 cap will lay flat, stay straight, retain fasteners, and provide a solid base for many types of stains and paints, giving you a post cap that will hold up to the elements for years to come.

Available for post sizes of 5x5, 6x6, 7x7, 8x8, 9x9, and 10x10.

Molding Depth: 1-1/8"

How to choose the correct post cap size:

Nantucket Post Caps are sized according to the actual physical measurement of your post.  All post caps are made 1/8" larger on the opening 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 come with an inside measurement of 3-5/8" x 3-5/8". 

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