ABSTRACT The anchoring strip of an elastomeric squeegee element is retained within the body portion of a plastic supporting strip; the supporting strip in- cludes laterally open channels which slidably engage op- posed sets of claws of a superstructure; a plurality of pairs of spaced apart openings extend through the web of one channel in alignment with corresponding pairs of openings in the web of the other channel and correspond- ing notches in the anchoring strip. The pairs of open- ings and notches are spaced apart from like pairs along the length of the refill unit so that at least one pair of opposed claws of diverse types of superstructures will fall between pairs of openings when the superstruc- ture is substantially centered upon the refill unit. A U-shaped clip embraces a claw and its legs pass through the pairs of corresponding openings and notches and are detachably retained. Indicia is provided to guide in centering the superstructure on the backing strip. Longitudinally spaced laterally broadened areas are pro vided to accomodate superstructures having wider dis- tances between opposed claws.
