Option “A” – sets consist of: two head casing mounted brackets, two sash mounted hangers and 2 traditional retaining clips. The clips utilize a carriage bolt and butterfly nut to pull the sash tight to the exterior casing or blind stop. In this case, no provision is made to allow for the propping open of the storm in pleasant weather.
Option “B” – sets consist of: two head casing mounted brackets and two sash mounted hangers. This set omits the retaining clips and are used with our popular SA-01 storm stays (purchase separately). This excellent system provides flexibility to secure the storm shut in cold weather. By choosing this system you have the option to easily prop open the storm for ventilation.
Option “C” – Half Sets. Use these when a window is already fitted with a storm sash using our brackets and a screen is desired for the warmer months. This set omits the brackets (because they are already present on your head casings) and the bolt, clip and wing-nut assembly (because you swap out the assembly from your storms).
