EasyFlex D-shape Marine Dock Edging protects docks and boats from damage while docked. Manufactured from durable, marine-grade fexible PVC, the D-shaped edging is engineered for vertical or horizontal installations on commerical or private boat docks and piers. EasyFlex 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 white throughout the material, unlike competitve "skin coated" top surfaces, EasyFlex Dock Edging will not show a different base color or scuff boat surfaces when nicked or scratched. The dock edging arrives in (8) individual 4' pieces, enough for a 32' installation. Install using EasyFlex 1-1/4 in. Galvanized Deck Screws (sold seperately) approximately 4 in. apart on top and bottom of edging.
