The Heavy Duty EZ Dock Piling Bracket has two key features. The first is a triangular roller system. This system allows your installer to set the rollers to the exact diameter sizing and position of your piling. This allows the dock to slide effortlessly up and down with changing water level and takes stress off the dock and piling. The second key feature is the rubber coupler system that connects the piling bracket to the dock. Rather than having a rigid steel bolt or welded connection like conventional dock systems these rubber couplers provide flexibility and energy absorption between the piling and dock. Providing a more fluid and less rigid solution that safeguards your dock system during storm events.
