ABSTRACT:
A single triple/twin wiper replacement carrier and blade unit for a twin wiper unit having parallel extending struts interconnected by a bridge is comprised of a flexible carrier formed by at least two or three essentially parallel struts defining a longitudinal direction, a bridge structure coupling the struts to each other in an essentially parallel relationship, at least two conventional wiper blades, each of the blades extending in the longitudinal direction essentially parallel to the struts, the blades being supported by and extending downward from the carrier and means for attaching the wiper replacement carrier and blade unit to a twin wiper unit wherein each of the struts is capable of receiving each of the blades. There are attachment elements for removably attaching the carrier to a twin wiper unit. The wiper replacement carrier may either be a triple or twin wiper replacement carrier, either of which may be removably attachable to a twin wiper unit.
