  • Impervious to Insects and Moisture
  • Will not rot, split, twist or warp

  • Quality craftsmanship
  • Made in the USA
  • Manufacturer: Nantucket Post Cap
  • Outstanding 25 year warranty on Material Defects


For a nail-free look, simply apply an exterior marine adhesive like 3M 5200 to the top of the post and slip the post cap over. Stainless steel nails may be used as an alternative, but not necessary.



Measure the length and width of your post for best fit. Order by actual post size. Base opening of solar post cap will be 1/8" larger to easily slip over your post and to allow the wood to naturally expand and contract.
