Post caps are made of clear western red cedar which is known for its beauty and durability in harsh environments. Cedar resists mold and mildew, plus its low density makes it less likely to swell, warp, cup or twist, as compared to other softer wood types.  

Product Care:

Nantucket wood products are sold in their "natural" state so they can be stained or painted to match or coordinate with any project. Because post caps are installed horizontally on top of the post, they receive the most sun exposure. Although you may leave cedar posts to weather naturally, manufacturer highly recommends sealing all wood caps before installation. Apply an exterior urethane stain or paint to all surfaces, including inside and under the base, to ensure long life. Many semi-transparent seals are available for cedar to maintain its natural look, while still protecting the caps.


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.
