A handle assembly is operable by user through a linkage to open and close first and second jaws, moveable with respect to axis. A ratchet assembly is included in the linkage and comprises a series of ratchet teeth and a ratchet pawl, which cooperate to maintain the jaws in a progressively closed position. A lock coupled to either the ratchet teeth, or the pawl maintains these elements in a spaced relationship to inhibit operation of the ratchet assembly until the lock is manually released. An insert carried by a jaw support includes a distal high-profile pad and a proximal low-profile pad, which may be covered by a woven mesh to enhance traction. An associated method includes the step of manually locking one of the ratchet elements in a spaced relationship with the other of the ratchet elements. <IMAGE> |
