Bubble weather stripping

Sir or Madame,

I have a double hung window from which the lower sash bubble seal has ripped from the bottom of the sash. I'm not sure which is the seal you indicate may be the replacement (# 58-171 or # 58-182). I enclose pictures in hopes that you can identify which it may be. The window sash is approx. 40" long and 16 3/8" high, the seal approx. 39 1/2" long The solid vinyl main body is approx. 1/2" wide, the foam filled "Bubble" about 1/4" in diameter, the "T" about 3/8" wide at the head of the "T". Please help, if you can.

Sincerely,

Fred 

Mam,

I understand. . . with a little silicone spray, I was able to remove the seal from a similar window and cut the seal in half lengthwise with a razor blade. Now I have several pictures at a closer distance for you to see, with which I have included a ruler for your reference. I was able to slide the two halves back together and reinstall the sash.

I hope this helps to identify the seal I need, thanks for your help.

Mam,

Thanks for your help, going to order # 58-171, since it looks slightly larger than the other number. . . if it turns out too large, we'll just order the other number. Seems like one of these should work, tough to tell by the pictures and diagrams. Thanks for your time.

Sincerely,

Fred
