* Glass size for push-out casements ** Units meet most national escape and rescue requirements F.S. = Frame Size • R.O. = Rough Opening • G.S. = Glass Size (Glass sizes are shown per sash)
NOTE: All measurements are nominal. Elevation charts are not to scale. 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. 216.
