I installed a 36" aluminum threshold with a raised gray vinyl
weatherstrip at my front door about 15 years ago. After 7 years the
weatherstrip needed replacing so I found one that would fit exactly
and popped it in. Another 7 years has gone by and again I need to
replace the weatherstrip.
It appears that the design of the weatherstrip has changed since I
last purchased one. From the top they look the same but they no
longer have the little "feet" or lip on either side which snap into
the threshold channel. Instead, they curl inwards to fit into the
threshold, and that type won't fit in mine.
Is there a source which still sells the older style vinyl
