Better to be safe than sorry, and when it comes to VELUX there are ways you can help secure your window. With the VELUX Opening restrictor you can regulate the extent to which your VELUX Roof Window opens with the easy-to-fit safety catch. This mechanism ensure that your VELUX window does not open too far if it is placed in an easily accessible place. 

The VELUX opening restrictor (ZOZ 010K S011) is ideal for extra security in a child's bedroom, ensuring it does not open too wide for them, whilst still allowing a restricted level of fresh air and ventilation into the room. 

The VELUX opening restrictor is suitable for centre pivot roof windows only (GGL & GGU) which have a height of 98cm or more.
