Window safety restrictors are the perfect device to help protect children and others from opening windows. Builders Window Supply is pleased to be the Nashville provider for Angel Ventlock window restrictors which are easy to use and perfect for any type of window.
We currently have the Retrofit Version available now.
The Retrofit 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 and 2010.
