The Chain Vice Grip provides maximum gripping power in any size pipe up to 6″ in diameter. EXTREME CAUTION must be taken when using the 5/8″ pin provided on the adjustment screw. Be sure than any off center weight is toward the locking direction (clockwise). Allowing more weight on the other side could loosen the jaws.
