YES 20
SYSTEM DESCRIPTION: YES 20 is a complete sash system intended to provide a framing system for single lites of glass. Glass of various thicknesses (3/16", 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", 7/8" and 1") may be glazed into the standard system simply by changing the glass stops and/or the gaskets. The gaskets employed are the same high quality gaskets developed for standard storefront systems by YKK AP and are therefore readily available.
