I need new weatherstripping on some older vinyl replacement windows. A few months ago I purchased what I thought was the right product: 39" Dual-durometer Weatherstrip, but it doesn't work. It's the right size but our current weatherstripping is all rubber/pliable, where the product I purchased from you is most hard plastic, and won't snap into the window channel.
Can you please help me find the right weatherstripping product for our windows? We have dozens that need new weatherstripping.
Thanks in advance for your help.
