Sea Breeze Flat Top Post Cap.  The size of the flat spot on top exactly matches the size of the post.  For example, if the cap size is 4" x 4", the flat spot will measure 4" x 4".

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.

Molding Depth: 1-5/8"

All Nantucket Flat Post Caps can be used in conjunction with a finial top (sold separately).

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.
