How to choose the correct copper post cap size:

Nantucket Post Cap LogoNantucket 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.
