Product Details

Foam-Filled Offset Bulb Weatherstrip with Fin - .187" x .375" T-Slot

T-slot bottom rail weatherstrip for vinyl single and double hung windows. Foam-filled offset bulb with integral fin compresses when the sash closes, creating a weather seal along the bottom rail. Slides into a 3/16 inch T-slot backing without fasteners or adhesive.

Replaces worn original weatherstrip in vinyl window systems where drafts and water infiltration develop at the bottom rail closure point.
