Dock Builders piling caps are an excellent and inexpensive way to protect costly pilings from internal rot. They are made from UV-stabilized polyethylene and are available in 1/2" increments ranging from 5-1/2" to 18" in diameter. Choose from round cone or round flat, in either black or white. The cone design helps to discourage birds from landing on them. In addition to the round piling caps, we also offer square piling caps (cone or flat) in many sizes ranging from 3-1/2” to 20”. Our black piling caps have an estimated life of fifteen years, while our white caps have an estimated life of nine years, though the actual life of the piling caps are not guaranteed.

Measurement / Installation Guidelines:
After all pilings have been cut to the appropriate height, measure the top of each piling at its widest point to determine which size piling cap is needed. Should the measurement fall between two sizes, then we generally recommend selecting the next larger size. Pre-drill each piling cap with three to four holes spaced evenly around the perimeter of the cap. Install the piling cap using stainless steel ring shank nails or stainless steel screws. It’s important that the pile caps remain round to ensure that the end result is aesthetically pleasing. To accomplish this, we recommend that you only install the fastener until it is flush with the pile cap (do not screw in tight against the piling). There may be some unnoticeable small gaps under the cap where the piling is not perfectly round.

High density polyethylene line holders attach near the top of pilings using two 60-penny nails or spikes. Line holders prevent dock lines from falling to bottom of the pilings and create a convenient holder for lines when the boat leaves the dock.
