Abstract: A torque-latch ring plier system includes a ring plier having a pair of opposed arms with opposed semi-circular segments forming an annular receptacle. A connecting link joins the pair of arms at the annular receptacle for pivotable movement. A lever is rotatably mounted to one of the arms at about its midpoint and is rotatable to engage a reaction device on the other arm for urging the arms to pivot about the link and close the opposed segments. A coupler is associated with the lever to enable a torque wrench to be connected such that operation of the torque wrench is effective to operate the pliers and establish a selected torque at the opposed segments. The system further includes a tilting bench plate for releasably holding a device to be tightened for angularly positioning the device for ease of access.
