I a member of Tite-loks pro staff. Take the metal and the rubber washer off of the screw and put the screw back in the hole on the T bar and tighten it down. This way you have metal against metal to tighten down. The holes in the washer doesn't have enough variance in the holes to allow you a slight adjustment. The way I am telling you to assemble it, your adjustment is infinite. If you have anymore questions contact me by PM and I can talk you through it on the phone. Thanks for buying Tite-Lok.........
