ABSTRACT:
A dual wiper extrusion including a pair of U-shaped squeegee support channels. Each channel includes an L-shaped extension to connect the extrusion to a wiper support assembly. The respective channels are smoothly contoured and joined one to the other by a bridging member located between the top and bottom limits of the extrusion to reduce cracking and failure of the extrusion during installation.
