Forgot to show the “old school” wheel collar method for an adjustable air restrictor for slowing the retraction and extension time. I don’t slow it down real slow just enough that it doesn’t slam super hard when it moves. Before installing the collar I grind the end of the set screw so it is smooth and round reducing the possibility of the screw cutting the air line. I believe that Spring Air sells a nifty adjustable valve to slow the air flow.
