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 Base Skirts 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 Trim 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.

These wooden post base skirts are available assembled or unassembled, and with Federal Trim (shown in photo) or Island Trim.  Post Base Skirt includes dressing base and top molding.

Deck Post Base Trim is available in sizes from 4x4 through 10x10.  Please email us for pricing and availability for sizes not listed here.

How to choose the correct post base trim size:

Nantucket Post Cap LogoNantucket Post Trim is sized according to the actual physical measurement of your post.  All trim is 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 trim would come with an inside measurement of 3-5/8" x 3-5/8". 

Dressing Base: 1-1/2" deep x 1-1/4" high
Federal Molding: 1-5/8" high
Island Molding: 1-1/4" high
