Andersen 400 Series Custom Head, Seat and Platform Boards


In support of our replacement product initiatives, Andersen is pleased to announce the availability of new custom-sized head, seat and platform boards for the construction of Andersen® bay/bow/box windows. Custom head, seat and platform boards will allow customers to leverage standard-sized Andersen 400 Series Woodwright, tilt-wash and casement windows into custom-sized bay/bow/box configurations.


These new custom head, seat and platform boards will meet California CARB (California Air Resource Board) compliance regulations. These boards will be eligible for placement on dealer-direct vans, typically with a 10-day lead-time. Please contact your Shepley Andersen representative for more information. By providing the Shepley Andersen Showcase existing rough opening dimensions, they will configure the appropriate units/boards and provide a quote.
