To install an inexpensive pinning device in a double hung window, drill a 3/ 16" hole from the inside window sash halfway through the outside sash at a slight downward angle. Then insert a nail or pin into the hole to secure the window. If the sash is wood, the pin can be made of such length as to set flush with the sash. A magnet kept nearby can then be used to remove the pin. The occupant must remember, however, that room windows are often used as a means of escape from burning buildings and at least one window in each room should be available for.
