If you are fitting a concealed window restrictor you will need:

  • A drill
  • A window restrictor

Step 1 : Select the restrictor and fit the restrictor arm

  • Hold the window with your hand move the window back and forth to simulate the window opening and closing while holding the stud in place.
  • When you are happy with the position and the restrictor closes smoothly mark off with a pencil where you want the stud to be placed.
  • Once positioned drill two pilot holes into the outer window frame.
  • Hold the restrictor in place over the pre drilled holes.
  • Using the drill, drill the screws into place.
  • Check the restrictor arm is firmly in place but that the arm can be moved as desired.

Step 2: Insert the restrictor stud

  • Feel the underside of the window inner frame.
  • Locate where you think the stud needs to be placed.
  • Hold firmly in place whilst drilling the stud into place.

Step 3:  Engage the restrictor and complete these final checks.

  • Pull the window in towards the closed position to engage the restrictor.
  • To release the restrictor gently push the arm towards the inside of the window to fully open the window.
