I'm hoping you can help me locate something on your website - if it is indeed available. I'm working with vertical sliding windows that I'm using your 28" / 380 series channel balances. What I am actually looking for is a sort of felt like material that fits into a groove on the back of the window sill that helps insulate as well as give the window something glide against so the window isn't just "metal on metal"... these windows are about 20 years old...but you have had every other "old" part I've needed...so I'm hoping the fact that I can't find it on your website...is just a matter of me not knowing the proper name by which to look it up. I'm attaching a picture as well...
I look forward to your reply as everyone there has been very helpful!
Sincerely,
Kevin
