Abstract
An improved window sash assembly which includes a sash held together by corner locks. The corner locks are all of similar construction, but may accommodate either tilt latch mechanisms or pivot terminal mechanisms. By utilizing a single corner bracket for both types of sash connectors, costs can be reduced and efficiencies increased. Additionally, the improved system imparts structural and sealing characteristics to the sash.
