As the humidity & temperature rises, keeping an eye on adventurous young children is very important as they can easily climb out of open windows. Therefore, parents, grandparents & nannies should consider some extra safety measures when caring for their little ones. The windows in your home can prove a real hazard when they're left open to allow the fresh air to circulate. Your children could be in danger of falling if a window is open too far, & if they're a bit curious, they may push a slightly ajar window open even further. Window locks have a simple 'slide & clip' action so windows can be left open without the fear of children climbing or falling out of them. They can be easily fitted & come complete with wood-screws. If you need to fit to UPVC windows, it will be necessary to pre-drill holes & use self-tapping screws.
