* Approximate glass sizes are given; true glass sizes vary depending on the radius involved ** Glass size for push-out casements *** Units meet most national escape and rescue requirements when ordered as venting units
† Push-out units only available with single-point hardware F.S. = Frame Size • R.O. = Rough Opening • G.S. = Glass Size
NOTE: All measurements are nominal. Elevation charts are not to scale. Divided lites are optional. Units are stationary as standard, however, some may be ordered as venting units. Contact your local dealer for details.
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.
