300B Series
Outswing Awning and Casement Windows
This product is no longer available for new projects, but we are happy to support existing 300B series windows.


The 300B featured casement or awning style operable vents. This window was essentially the same as our classic 300A series window, but instead of a multi-point locking system the 300B series utilized a cam handle.
