Are Window Restrictors child-safe?
There are several options available that make it more awkward for children to manipulate the restrictor device. The R02 is designed for a two-hand/two finger operation, the R03 is a fixed restrictor (no release) and the R04 is key-locking. The restrictor should be positioned on the window to ensure the air gap is no greater than 100mm (10cm), the size of a child’s head.
