Help with Installing the 58-164

Question

Just purchased one of your dual durometer weather strips for my new vinyl window, part 58-164. This seal was not installed on one of the windows by the builder, therefore I'm installing. I can see it is the correct seal but having trouble installing. The T-shaped part of the weatherstrip is very stiff and doesn't snap easily into the groove in the window. Is it just a matter of hand strength, or is there some technique? I heated the weatherstrip a bit with a heat gun which made it more pliable, but still won't snap in.

Hello!

The 58-164 isn't meant to snap into the slot. It's actually meant to slide into it from the end. Most windows that take this type of seal have an opening at one end of the channel that allows this to be done. If there isn't an opening, you'll have to make one. Take a look at the video below and see if this helps. While the video shows wool pile, not bubble seal, the process is the same.
