our windows safety restrictor is safe
 |
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 (10cm).
Fensters’ WSR TM. not only provides the recommended safe maximum opening but it does it by means of a child proof locking device. The lock can be key dead locked or left in the push to release mode - requiring a two handed operation to release the plastic coated, high tensile steel cable.
Safe limitation of your window opening to a maximum of 4 inches (10cm)
Child safe locking system
Designed to withstand a minimum operating force of of 1,200 Newtons (twice the BS recognised standard of 600 Newtons)
Modern clean lines and a choice of RAL colours and cable lengths means you will always meet the needed specifications
