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'. Review: Works for a small gap on well hung door - This worked perfectly for a door replacement insulation gap filler. I tried several times to use what Home Depot was selling, but it was too big and I couldn’t shut the door. Then I returned it and tried a different kind. Then I returned that too. A week later it started falling out of the track. I’m going to have to stuff something else in there along the spline. I shoved some thin rope in the gap - about the width of half a shoelace - alongside the spline and it’s fine now. ## Features - Manufactured in USA from exceptional OEM+ quality Thermoplastic Elastomer (TPE) - 6 Lengths and 4 Color choices to match most all applications - Standard 3/16” Kerf depth and 1/8” Kerf width - Most common 1/4" Bulb Diameter with 1/32" Material Thickness ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06Y1TCHNH | | Best Sellers Rank | #31,400 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #164 in Weather Stripping | | Brand Name | Seal Supply | | Color | Brown | | Customer Reviews | 4.5 4.5 out of 5 stars (499) | | Item Thickness | 0.03 Inches | | Manufacturer | Seal Supply | | Material Type | Thermoplastic Elastomer | | Recommended Uses For Product | Windows,Window,Door | | Unit Count | 50 Count | ## Product Details - **Brand:** Seal Supply - **Color:** Brown - **Item Thickness:** 0.03 Inches - **Material:** Thermoplastic Elastomer - **Recommended Uses For Product:** Windows,Window,Door ## Images ![Window Weatherstrip Seal 1/4" Bulb Bubble Kerf Mount 4 Colors & 6 Length Options - Image 1](https://m.media-amazon.com/images/I/71XhrkTFgRL.jpg) ![Window Weatherstrip Seal 1/4" Bulb Bubble Kerf Mount 4 Colors & 6 Length Options - Image 2](https://m.media-amazon.com/images/I/718tWElUgML.jpg) ![Window Weatherstrip Seal 1/4" Bulb Bubble Kerf Mount 4 Colors & 6 Length Options - Image 3](https://m.media-amazon.com/images/I/71yPVh+4hDL.jpg) ![Window Weatherstrip Seal 1/4" Bulb Bubble Kerf Mount 4 Colors & 6 Length Options - Image 4](https://m.media-amazon.com/images/I/81JKi5ZYBaL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Outstanding. *by A***R on January 17, 2026* Took 1.5 hours to do 8 windows.
