Product Details
Compliant with ASTM F2090-21
The Side Fix version is for use on timber, vinyl, aluminum and fiberglass sashes.
These devices are primarily factory-fitted as access to the side of the sash stile is required for fixing. However, provided the sashes can be removed easily, the Side Fix version is also suitable for after-market use.
Two screws are used to fix each device in place. Fixing is through the side of the sash stile and into the threaded holes in the device. Screw holes are not visible from the front of the window and the units are therefore tamper-proof.
These units have been Focus group tested and have been proven to be operable without prior knowledge or tools.
IMPORTANT: Window manufacturing and device fitting is subject to tolerances beyond our control. For this reason, it is the responsibility of the window manufacturer and device installer to ensure that the recommended device works with the window’s tolerances and that the device has been installed correctly, operates correctly and resets correctly otherwise the safety features provided by this device will not work. If the device does not reset correctly, it will not comply with ASTM F2090 regulations and will not be fit for purpose.
How Does Angel Ventlock® Work?
By restricting the opening of your double hung window. Angel Ventlock® allows you to open the window for ventilation whilst making it impossible for young children to open the window far enough to get out. For adults however, it is simple to open the window fully by following the steps below.
Once fitted the Sash will stop when opened to 100mm
Simply press to release (repeat on opposite side)
The window can be easily raised fully without a key
The arm automatically resets to original position once closed
