In the spring, summer and fall this EZ Dock Trail system will sit in the water about 1.5”. In the winter when this pond freezes the dock will lift up on top of the ice. The rubber couplers will allow the trail to flex in all direction allowing the dock to move and drastically reducing the risk of damage from ice movement. Notice the damage to the previous trail/bridge on the right in the image. 10” piling and just ten years old.
