A Product Description

Product Description

The Fenster window lock can be used as a window or door restrictor to safely allow ventilation into the room without the risk of them exiting. This device is a brilliant childproofing device designed to prevent your children from potential dangers around the house. With child casualties rising on a yearly basis Fenster have invented a simple but effective lock to drastically reduce the number of children from falling out of windows or doorways leading to the risk of injury.

Regardless of the window type there should never be an instance where a vulnerable child or adult has access to a window opening greater than 4 inches, the Fenster window and door restrictor aims to eliminate this. With a modern clean look and choice of colours the Fenster safety restrictor will fit all household interiors and exteriors. The robust design of the door and window lock also ensures that the cable cannot be cut without the use of specialist tools.

  • Simple operation by means of key locking or push to release button
  • Easily installed by the homeowner
  • No need for bespoke hardware to suit the window cavity dimensions
  • Fits all window and door types
  • Designed to withstand a minimum operating force of 1,200 Newton's (twice the BS recognised standard of 600 Newtons)
  • 20cm Cable
  • can be used in commercial buildings, schools, caravans as well as at home

Easy to fit and use. Feel much happier children are safe.
Only downside is when it is removed holes are visible in window frame


Easy to fit, looks good, does the job


Very good


Easy to fit and looks good once installed! Also liked the added bonus of button to open window in emergency as fitted on our fire escape window upstairs in our sons room. Would highly recommend.


Super safe but tricky for a non-diyer to install
