WE have Kolbe double hung, tilt in windows throughout the house. Due to age (about 30 years)many of the window mechanisms break when the windows are tilted in. When this occurs the window will drop to its lowest position as nothing is holding it in place. Each broken peice had a white cord attached that aided in raising the window.
Are replacement parts available, what components shoud I purchase and do you have a video on their installation?
Thanks,
Bill
