This 7″ Round Copper Flat Piling Cap offers reliable protection for dock pilings while delivering a clean, low-profile appearance. Designed to fit standard 7-inch diameter pilings, it shields the piling top from sun exposure, rain, and environmental damage that can shorten piling lifespan. Made from marine-grade polypropylene, this piling cap resists corrosion, cracking, and fading even in demanding coastal environments. Its flat-top design provides a subtle, finished look that complements both residential and commercial dock installations. An excellent alternative to metal caps, this polypropylene piling cap is lightweight, durable, and requires no maintenance once installed.
