I have a few windows that just fall down and won't stay up. It looks like there is no rubber in the track at bottom of each side. Please direct me to the part name..thx

I am a little confused with your inquiry. As I started to read it, I immediately thought of channel balances as being the main reason why your windows will not stay up. However as I read on, you mentioned a rubber track and then I see you also referred to our 26-139 single hole aligner. If you could verify what type of part you are inquiring about and include some photos, that would be very helpful to us.

It looks like there is suppose to be a cube shaped piece in the channel to hold window from falling Can I buy just the cubes?
