How to Measure

  1. Measure the depth of the window frame where the end posts will be attached (inside right and left sides of window frame). *If the depth of the frame is less than ¾ inch, the guard will need to be installed on the outside of the window frame (on the molding or wall around the window). The end posts are ¾ inch wide and need at least that much space for installation. Please note, the end posts need to be screwed into solid material or stud for proper operation. 
  2. After determining where the guard will be attached (inside of window frame or molding/wall outside frame), measure the width of that area. This will determine the width of the guard required for your window. 
  3. Measure the height of the window opening with the window fully openThis will determine the style of the guard you will need. The guard is available with 3, 4, and 5 bars. We recommend using multiple guards for double-hung windows since both top and bottom windows open. Therefore entire height of window must be measured or window stops may be used to keep top window from opening beyond desired height.

If the window opening exceeds the specified "maximum opening" size, more than one guard will be required to cover the window.

For more detailed measuring instructions and window guard model reference, please consult the Double-Hung Window Measuring Guide.
