The 90° Dock Corner 6" x 6" Black PVC is designed to protect exposed dock corners where straight dock edging meets at a right angle. Manufactured from high-quality marine-grade vinyl, this dock corner provides durable impact resistance in high-traffic docking areas. Featuring internal structural ribs, this corner bumper helps absorb impacts from boats and watercraft while maintaining its shape and performance over time. The black finish creates a clean, seamless transition with standard dock edging and is ideal for residential docks, marinas, and commercial waterfront installations.
