I have a Marvin replacement Windowd, the channel balances keep releasing the string to the shoe and the. The window won't stay open. . I will be replacing both channel balances but would like to place the shoes as well. The channel balances are labeled 1530 CL and a are 16" long. They are NOT ribbed .Based on the photo, do you have this style channel balance and shoe and if so, what are the part numbers?
Thank you for your time and assistance.
