Paper Towel Holder Tensioner

This is a fix for the Kamenstein 4536 Perfect Tear Paper Towel Holder. Although a quick search on Amazon shows other manufacturers (Cuisinart) with the same tensioner design.

I loved this paper towel holder when I first bought it. But after a few months of use, the internal tensioner, which is a small plastic piece, slowly started losing it's teeth. With only 4 total teeth, the loss of any causes the holder to hold no tension on the paper towels. It's been like this for a year
