Vinyl Window Weatherstrip Identification

A home owner from Eastern Pennsylvania says:
I think I need 39" Dual-durometer Weatherstrip Product Code: 58-164, but I am not sure since mine looks slightly different than yours.

There are no markings on the windows that would identify the manufacturer so I have been having trouble locating replacements.

It installs in the window in a channel. The outside measurement is about 3/8" and the 'T' part is 3/16". The bubble is 1/4".

If I do purchase these, what is your return policy should they not fit once I receive them?

The 58-164 may work, though it's a bit stiff. Our 58-182 may be a better match. For more information on returns, see our return policy.
