The Angel Ventlock

Side Fix - Single Action

The Side Fix version is fitted into the stiles of the Top Sash - one on either side.

The units are single action, so fitting two ensures compliance with ASTM F2090 2008, 2010 & 2017


Product Description

These units have been Focus group tested and have been proven to be operable without prior knowledge or tools.

The unit is primarily factory fitted as access to the sash is available prior to installation in the window frame. However, provided the sashes can be removed easily, the Side fix version is also suitable for use where the sashes have already been installed.

Two screws are used to fix each unit in place. Fixing is through the side of the unit and into the sash. Screw holes are not visible and the units are therefore tamper-proof. The Side fix version is for use on Timber, Vinyl, Aluminium and Fibreglass sashes.

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/or installer to ensure that the correct product is specified and fitted. The installer must confirm that the device operates and resets correctly otherwise the safety features provided by this product will not work . If the device does not reset correctly it will not comply with ASTM F2090-2008, 2010 and 2017 regulations and will not be fit for purpose.
