Remark:
1. To clamp the 2 3/8" tubing, special dies must be ordered for Model XQ 89/3YB, 3YC;
2. Advantage of Model XQ89/3YE; Low speed, rated speed is 28 rpm. Dies of backup tong can clamp the underside of tubing coupling, so as to reduce distortion of tubing coupling to prevent conglutination of thread.
