Use this hardware to make a stiff arm to hold your dock in place. The stiff arm is a system developed to be used as an alternative to piling to anchor your dock in place. This system is great when you have a single dock that runs parallel to the shore. Its self tending and has the ability to rise and fall the distance of the length of pipe you use.
