These wipers remove excess wall cake to improve cement-to-formation bonding by producing a wiping action during running and reciprocation. A continuous, interlocking and overlapping loop of tempered-steel wire cable is laced into the hinged collars. A bolt holds the wipers in position and eliminates the need for stop collars. A hinged version is also available.
