Hey, John. Usually a stamp of 23 1 corresponds to our 2310 option, yes. However, you should weigh your window sash just to be sure this is the right way to go.
Ok, I installed the new channel balances but I got the same behavior that I was getting with the originals before the spring broke. Slide the window back down over the clipped in channel balances but the balances do not catch the window. As if maybe something is missing within the channel of the window?
I then broke the channel clip so now I need to order some of those so I can get the window out.
Any thoughts would be helpful.
Thanks,
John
