Round Flat Piling Caps

DockBuilders’ piling caps are an excellent and inexpensive way to protect costly pilings from internal rot. Our flat-top caps are made from UV-stabilized polypropylene (polyethylene for >16” caps) and are available in ½” increments ranging from 5” to over 18” in diameter.

• Clean Profile: The flat design provides a sleek, low-profile look for your dock pilings.
• Premium Materials: UV-stabilized construction to prevent cracking and sun damage.
• Estimated Life: Black piling caps (15 years) / White piling caps (9 years).
• Precise Fit: Available in 1/2" increments from 5" to over 18".

In addition to the round piling caps, we also offer square piling caps (cone or flat) in many sizes ranging from 3½” to 20”. Our black piling caps offer the longest service life, though the actual life of any piling cap is not guaranteed.
