My door sill weatherstripping on pre hung steel insulated door needs replacing. Ive seen ones that slip up on the bottom of door which I have and am repacing. But I ,ve never seen one for bottom plate/ threshold. Any suggestions please?
Not everything they sell is sold on line.
Bring in a sample and tell them what it's for.
I've been replacing those things for at least 30 years in 4 different states and every "hardware" type store had them in stock because they were just a really bad idea to begin with and were sure to fail.
I've replaced all my thresholds with adjustable ones with the seal on the door.
