VELFAC restrictors Window opening restrictors are designed to limit the opening distance of a window, and are primarily a safety feature. All VELFAC opening restrictors are concealed within the sash and cannot be seen on either the inner or outer frame when not in use. VELFAC offers two types of restrictor: Hand operated restrictor These limit window openings to 40mm and can be released by hand to allow the window to be fully opened. Tool operated restrictor These limit openings to either 100mm or 210mm (depending on window size) and cannot be released by hand – a special tool is required to fully open the window.
