    The body (Part A) should be attached to the fixed frame and the foot plate (Part B), to the opening window frame.

    The exact position should be decided prior to fixing in order to determine how wide the window should open. Measure a maximum of 100mm from Part A to Part B; 100mm is in accordance with health and safety regulations to prevent the passage of a small child.

    To fit, Part A should be held in the desired position on the window frame, mark the screw holes, Jackloc advises drilling pilot holes with a 3mm drill bit. This should be repeated for Part B on the opening window frame. Then simply fit Parts A and B using the screws provided with your window restrictor to the marked holes with the window closed during fitting.
