Fitting & Usage

The following describes fitting of the cable restrictor to a typical window.

Fitting key-locking cable restrictor to a window

  1. Firstly, determine the maximum opening that you require (100mm or 89mm for child safety), how many cable restrictors you need, and where they should be fitted. Refer to Fitting Considerations for help with these decisions.
  2. Remove plastic cover from Lockable Fixing Block. You can release it by holding the sides of cover and pushing the key way.
  3. Hold the Lockable Fixing Block in desired position on the frame, and mark the screw positions. Set the Lockable Fixing Block aside and drill a 2mm pilot hole at each screw position.
  4. Reposition the Lockable Fixing Block and secure to the frame using two of the supplied fixing screws.
  5. Lock the plug at the end of the restrictor cable into the Lockable Fixing Block. This will make it easier to accurately position the Cable Plate on the window.
  6. Open window to desired maximum opening, and position the Cable Plate so that it sits flat on the window and the cable is taut. Mark screw positions on the window. Consider that any slack on the cable would mean that the window may open wider than desired.
  7. Let go of the Cable Plate and drill a 2mm pilot hole at each screw position, and then secure the block with the two remaining fixing screws.
  8. You can now test your restrictor by making sure that you can lock and unlock the cable, and that when locked, the window does not open more than the desired maximum.
  9. If the restrictor works as intended, you can now push-fit the plastic covers over the Cable Plate and Lockable Fixing Block.

Note that the above principle also applied to use of the restrictor on a door.

Fitting Considerations

To comply with window and balcony door safety requirements (EN 13126-5:2011 + A1:2014), opening should be restricted to a maximum gap of 100mm, or 89mm where child safety is a consideration. When being pushed open, the restrictor should take a minimum load of 35Kg. Therefore, it may be necessary to fit multiple restrictors. It is recommended that restrictors are fitted to the side opposite the hinges, and that if one restrictor is used, then it is fitted centrally.

To meet European safety standards, the maximum opening should 100mm, which should be reduced to 89mm for child safety.

Cable Restrictor Maintenance

The cable restrictor can be kept looking good, and operating well, with just an occasional wipe using a damp cloth, and a little light oil.
