Replacement weather seal

The part needed is for the outer edge of the bottom sash of Gorell windows. See the two photos. The bubble is 1/4". The stripping is T-shaped, with the outside strip at 7/16", the inside strip at 3/8" and the depth at 1/8". I will measure the quantity needed if you can supply this part. Thanks for this wonderful service.

Looking more closely at your offerings, I think what I need is your .270 T-slot, part #58-171.

If you agree, I'll order three of the 12-foot strips.

Please advise.

Thanks.
