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.
These units have been Focus group tested and have been proven to be operable without prior knowledge or tools.
Primarily fitted as an after market device where access to the sash is difficult.
This type can also be installed as a Factory fitted device to avoid interruption of assembly lines.
Includes two devices for attachment to both sides of the sash. Two screws are used to fix each unit in place. Fixing is
through the front of the unit and into the sash.
For use primarily on Timber and Aluminum windows. Can
also be fitted to Vinyl and Fiberglass units where suitable fixing is
available.Click here to download the installation instructions.
