The innovative Angel Ventlock® system was designed and developed to prevent children falling from an open sash. The patented system restricts the sash opening to 100mm (4 inches) without compromising emergency egress. Safety restrictors fitted to windows sold in the EU need to be tested for load bearing capacity. Our restrictors have been tested in accordance with BS EN14351-1:2006 and ASTM F2090-2008 & 2010 to 350N.
