Product Details
Foam-Filled Offset Bulb T-Slot Weatherstrip - .187" x .300"
Amesbury bottom rail weatherstrip for vinyl single and double hung windows. Foam-filled offset bulb slides into a 3/16 inch T-slot backing in the bottom rail. Compresses when the sash closes to seal the gap and block drafts and water infiltration.
Fits Atrium vinyl windows, MI-series windows, and many other vinyl window manufacturers using standard T-slot bottom rail profiles. Replaces original weatherstrip when degradation or wear allows air and water leakage.
