How to install

The Door Defense is easy to install, requiring little more than a power drill with a screwdriver bit, a pair of scissors (or a utility knife), the Door Defense kit, and just a few minutes of your time.

Instructions for installation:

  • Remove any existing weather-stripping from the doorframe
  • Measure the distance from the floor to the bottom of the doorknob hole on the doorframe
  • Remove the top OR bottom tab on the Door Defense unit so that the unit matches the height of doorframe from the floor to the doorknob hole on the doorframe
  • Cut the weather-stripping at the point on the Door Defense unit where the tab was removed
  • Position the Door Defense unit over the existing deadbolt and doorknob holes
  • *Optional: Using a 1/8-inch drill bit, drill pilot holes in the screw hole locations on the doorframe
  • Using the screws provided, attach the Door Defense to the door frame
