Good morning, please recommend repair parts for my windows. The windows are single hung, vinyl windows, bottom tilt, about 15 years old. The lock shoe (marked with patent #4610108) looks like your part number 15-195B and have the same dimensions.
The tilt channel is 9/16" wide, ½' deep and 32" long, stamped with "32B BS1". A single screw attaches the cord from the channel to the top of the window sash and to the coil spring inside the channel balance. I have attached photos.
Thanks
