Window Opening Control Devices

The Marvin Family of Brands is committed to safety. For this reason, we offer several windows with factory applied Window Opening Control Devices (WOCD’s).

Window Safety

The Marvin® Family of Brands has always been committed to creating quality window and door products. As a company with a strong family legacy, we take the safety of our customers and their family seriously. Windows in a home should bring light, fresh air and a view. But, it’s important to recognize that window screens are only intended to keep bugs out, not prevent a potential fall.

Our Window Opening Control Devices meet the ASTM F2090-10 standard, a code created to assist in the prevention of window falls in children under five years old. To meet the standard, our devices limit the window’s net clear opening to 4” or less when the sash is opened and have a release function allowing the window to fully open. In order to meet the safety standard, WOCD disengagement takes two independent actions upon re-opening which helps prevent accidental release. Devices will then automatically reengage once the window is closed and again limit the window opening to 4”.
