## Description

Bubble Kerf Mount Window Weatherstrip Seal 1/4" Bulb, Stiff Kerf Easily Applied to The Slot 19.68Ft (1/4", 19.5FtBlack) - desertcart.com

Review: Worked very well and met tolerances. - I had to return another version and order this one with the stiffer inserts as the tolerances on our Marvin door were extremely tight. Still a tussle, but this worked and I was able to replace the weatherstripping with a bit of ingenuity and elbow grease.
Review: Quality product, very useful - I used this as a seal for my attic hatch. For dusty or high-wear environments, adhesives are not a good idea; it’s better to have kerf-mounted seals/weatherstrip. As such, for my attic hatch I cut slots (1/8” wide, 1/2” deep) for the kerf of this weatherstrip to be pressed into. This product fit well, and forms a great seal to prevent attic air from entering my garage. Note: the kerf on this product is centered along the width (looking at a cross section). If you need weatherstripping for doors, they usually require the kerf to be on one side, as the door jamb slot touches the jamb itself. This would be good for windows, however.
