Double pole weatherstripping from a vinyl casement unt

Thanks for reaching out to us. I am familiar with this foam seal. While I'm not 100% certain of this, I don't believe this is made anymore. The best option we have for you is our 58-170B, but it's not a confirmed match. Some customers have told me it installs well, others tell me that the kerf is too narrow to fit in the window.

Either way, it is our best and only option. Review its specs below and see what you think.
