square newel post cap surface treatment:hot galvanizing or electrogalvanized Available in 1/2" increments from 5 1/2" to 18

Available in 1/2" increments from 5 1/2" to 18" diameters.

Measurement Guidelines:  Measure the diameter of your  piling from the widest point across the top to determine the size piling cap needed.  If your measurement falls between 1/2" increments, it is recommended to go with the next larger size.  The piling caps will stretch approximately 1/4", but ultimately it is your decision whether to purchase a smaller size based on the measurement of your piling.

These easy to install piling caps are an excellent, inexpensive way to protect costly pilings from internal rot. Install by drilling nail holes and attaching with galvanized roofing nails or stainless screws. We recommend stainless steel 1 1/2" length ring-shank nails.  For round piling caps, 3 nails or screws are required.  Place in a triangular fashion along rim of piling cap when securing piling cap to piling or post.  (Note: Using 4 nails or screws tends to make the piling cap pucker and is not recommended) 

Dock Accents uses a reputable manufacturer who provides piling caps made from polyethylene (approximately 1/10mm to 2/16" thickness) with an estimated life in excess of fifteen years for black caps and in excess of nine years for white caps (actual life of piling caps is not guaranteed).
