Angel Ventlocks® are Window Opening Control Devices (WOCDs) and were specifically developed to restrict the amount a sash window’s lower sash can open. Fitted and used properly, they can prevent your child from opening the sash far enough to fall through. They do not require a key to operate and are unique in the way they reset automatically when you close the window.

Please view our video for more information on fitting and using an Angel Ventlock to keep your child safe.

The Face-Fix Angel Ventlock® is fitted into the face of the stiles of the top sash, one on either side. The units are single action, so fitting two ensures compliance with ASTM F2090-21.
