YES 40 FS - Commercial Storefront System

The YES 40 FS is a center set, flush glazed storefront framing system designed primarily for 1/4" glass or infill panels 1/4" to 3/8" thick. This architectural commercial storefront system will accommodate YKK AP's patented hinged mullion, as well as our flexible mullion; these mullions allow more creative freedom where curves and angles become a functional part of the design.
