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

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.

This weather seal is made of quality rubber that keeps its shape and seal’s very good.

The kerf came away from the weatherstrip seal. Would not recommend.

Needed a thinner seal which this was but this is some kind of rubber so it drags on the door when opening or closing. I had to trim the bulb - round part of the seal with a razor blade so it barley touched the door, now the door moves easy and there is no noise from the seal dragging against the door. My door was painted over the metal so that likely made it stick more. Though I had to work it I now have a free moving door that seals well.

Simply fit into the slot on the bottom of window. Easy peasy replacement

Fit my window slot same as factory seal

The kerf insert did not fit my kerf size.
