Hello, Bill & Bill. I am working on getting it all lubed & cleaned. At full width opening with the pivot, they are offset approx. 5-10 degrees from 90. With the pivot closed, the angle looks approx. 45 degrees. I will cut a few test pieces and get back to you. Re; Wetzler, sad to hear they closed their doors, I try to buy Wetzler clamps whenever I get the chance. Regards, Lou
