Channel balance

Dear Sir/Madam,

Is it possible that some kind of sashes are not allow people to removal? I checked my window and find it seems the channel balances are mounted to the two sides of the sash directly. My house was built on 1987. Thanks!!

Thanks!! I will take some pictures and send them to you after work.

There are seven windows on my 1987 townhouse. I plan to replace the channel balance for all of them. But I can't figure out how to remove the sash after read a lot of articles from internet. For example, I can't push the sash right or left. There is no any space between the sash and frame I think. I checked my windows and found that the channel balances are mounted to two sides of the sash directly. There are two take-out clip on each side. One is on the top and the other one is on the middle. The top one can be easily remove. But the middle clip is hard to take out because it is almost be blocked by the sash. I attach some pictures. I guess the solution probably is remove the plastic cover. Am I right? I will take more pictures if you ask me to do that. I am very appreciate for any help from you. Thanks. Yunqi

Dear Sir,

My windows are no-til.

Thanks!

I got it! But I have another problem. I found the weatherstrips, that slide in the lower sash, need to be replaced. The cross section of it is very small. Do you have it? Or do you have ant solution because I think it's hard to find it.

Dear Sir/Madam,

Two parts need help. Top sash guide: I need the part number. The height of my top sash guide is about 2". As for the top attached, I find two parts are close to mine. First one is 19-031, but I am not surt the position of the rivet. The other one is 19-037. This one looks almost the same with the picture. But the width of mine is about 1" while yours is 1-13/32". Maybe I have cut the left and right wine to fit the size.

Thanks.
