You can buy the hardware at 3 places online. Dock plans show how to make them in sizes you can move them by hand in and out between seasons. If left in, the ice will bend the poles and crack the stringers so take it out just like you take out your boat and boat trailer. Ice is very powerful and it moves, expands, floats down stream and tilts on the shoreline. We are a Maine manufacturer where docks need to come out 7 months out of the year by law and because of the ice. This is rare but ice has been known to push up on shore and destroy docks that were stacked above the waters edge. Our aluminum frames are also built in sizes that can be removed by hand. We offer removable decking so the frames are lighter. www.dock.shop greatnortherndocks.com/stationary-pipe-hardware/dock-hardware-pipe-leg-support/ and at www.amazon.com/greatnortherndocks
