Dock post bumpers are protective devices designed to shield dock posts or pilings from damage caused by boat impacts. They are typically made of durable materials such as vinyl or foam and are installed around the posts on a dock. Dock post bumpers absorb the impact energy when a boat approaches the dock, preventing scratches, dents, or other damage to both the boat and the dock structure. These bumpers contribute to the overall safety and maintenance of docks in marinas or waterfront areas.
