* The first number of the glass size height is the height (per sash) for each flanker sash. The second number is the glass height for the center picture unit. U.D. = Unit Dimension • R.O. = Rough Opening • S.O. = Sash Opening • G.S. = Glass Size
NOTE: All measurements are nominal. Elevation charts are not to scale. Divided lites are optional. Center picture units are only available with a 1-3/4" sash. Flanker sash must be specified as either Traditional or Sterling sash when ordering. If the cable support system and/or insulated platforms and support brackets are not being used, other means of proper support must be used. Add 1-13/16" to the R.O. height if an insulated platform is being used. R.O.’s for bay units without head and seat boards, typically used for walk-out applications, are different. Some installation procedures will require a larger rough opening than noted (i.e. installations utilizing our installation clips), therefore, you may need to increase the rough opening size accordingly. Rough opening gaps may be increased up to a maximum of 1/2" on all sides and still be within good practice guidelines. For rough opening recommendations, see pg. 216. The side jambs of double hung units extend above the head jamb; additional space for the rough opening height may be necessary.
