Bulb seal for bottom sash MI windows

Thanks for posting. Most MI double hung windows use our 58-182 T-Slot foam filled weather strip. There is no adhesive necessary, it just slides in from the side. In order to confirm if this will work for you, you'll need to remove the sash and slide out the old seal to confirm how well our measurements and profile match up.

I'm afraid we don't have product information for the weatherstripping shown to us by that customer. They had requested a possible match, but without better photos the best we could do was make an educated guess. We never received verification as to whether our suggestion was correct or not.

Your next step should be to compare your weatherstripping to the dimensions and design of our 58-182. If that doesn't match, we would need clearer photos and written measurements in order to make a better suggestion.
