## Description

Window Weatherstrip Seal 1/4" Bulb Bubble Kerf Mount 4 Colors & 6 Length Options - desertcart.com

Review: Good durable seal for windows. - Good quality bubble kerf seal. I used it on my windows for the bottom seal and it worked perfectly to replace the OEM product. The round bubble seal is of a decent thickness so I am optimistic that it will last longer than the OEM product that was almost paper thin and had collapsed. The kerf mount went into the groove without any significant difficulty and held the seal in place firmly.
Review: Great weatherseal - Great weather seal. The kerf is strong and well attached to the bulb. Bulb is soft but strong. Worked great for replacing all the weathersealing in our double hung windows.

Great weather seal. The kerf is strong and well attached to the bulb. Bulb is soft but strong. Worked great for replacing all the weathersealing in our double hung windows.

### ⭐⭐⭐⭐⭐ Outstanding.
*by A***R on January 17, 2026*

Took 1.5 hours to do 8 windows. Previous product (soft kerf) took 2.5 hours to do 4 windows. Very easy to install with rigid kerf. Also has a better seal than previous product. Ordered another 18'.
