ProFlex 10 ft. D-shape marine dock edging protects docks and boats from damage while docked. Manufactured from durable, marine-grade flexible PVC, the d-shaped edging is engineered for vertical or horizontal installations on commercial or private boat docks and piers. ProFlex marine dock edging products contain UV inhibitors and will not crack, rot or deteriorate when exposed to sun or temperature extremes and are unaffected by oil, gasoline or saltwater. Colored black throughout the material, unlike competitive skin coated top surfaces, ProFlex dock edging will not show a different base color or scuff boat surface when nicked or scratched. The dock edging arrives as a single 10 ft. Coil in a box. Install using ProFlex 1-1/4 in. Galvanized deck screws (sold separately) approximately 4 in. Apart on top and bottom of edging.
