A perfect complement to the Dryer Wall Vent in applications where stucco or lap siding requires a mount over the house wrap, the AZEK® brand block is made from solid cellular PVC and perfectly sized for mounting the vent. They're about as workable as wood (can be cut, routed or mitered), are impervious to moisture, and they are durable enough to last as long as the Dryer Wall Vent.
