I have MI Windows model 9555 double hung windows from about 25 years ago. I need bulb seal replacement for the bottom sash. Is your product 58-182 a correct fit? If not, what is the correct selection? Thank you.

Hello,

We are not able to make out exact dimensions from photos, but I agree that either the 58-171 or 58-182 would be our best replacement options. Review the specifications below to confirm the best fit. Thanks for posting!
