i cannot find this metal strip anywhere. i am being told it is not manufactured anymore.

years ago, instead of using caulk, the countertops in the old kitchens did not have backsplashes. instead there was a thin metal strip that went on top of the end countertop & the wall the countertop was against.

***** & ********** are telling me this strip is not manufactured anymore; they cannot order it. i can't believe this is true. can this product still be purchased? if so, where?

thank you.
