F.S. = Frame Size • R.O. = Rough Opening • G.S. = Glass Size
NOTE: All measurements are nominal. Elevation charts are not to scale. Radius units are sash set as standard. Direct set units are available but glass sizes differ from chart shown. Contact your dealer for details. The units shown are stand-alone units. Adjustments may be required when stacking over other units; adjustments will be made in the factory. Divided lites are optional. Divide lite pattern options are shown on pg. 126. 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.
