By restricting the opening of your double hung window, Angel Ventlock® allows for ventilation whilst making it difficult for children to open the window. For adults however, it is simple to use and the window can be easily opened and the device reset by following the steps below. Fully compliant with ASTM F2090-21.

How does Angel Ventlock® work?

1

When you open the window, the sash will stop when opened to 100mm

2

Simply press to release (repeat on opposite side for single action devices)

3

The sash window can then be easily raised fully – no key required

4

When you close the sash, the device automatically resets and arms itself.
