*Approximate glass sizes per sash are given; true glass sizes vary depending on the radius involved. 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. The venting of the bottom sash of half-circle top units is limited due to the radius on the top sash. Divided lites are optional.
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. 194. The side jambs of double hung units extend above the head jamb; additional space for the rough opening height may be necessary.
