Mine uses a hitch mount for the flagpole. My pole is just a twist lock and if it is too windy it drops down a section or more. I have thought of drilling it for pins but thought maybe it was better to let it drop down if the wind was that high. even all the way down the flags are still off the ground. No climbing, just drop the pole in the mount, pull up the top section and put the mounts on then top ball and the flags and start sliding it up as high as you want.
