Product review (5 stars): Highly recommended for Kenmore stove/ovens
I bought two of these because our Kenmore stove/oven's door supports were cheap.  The Kenmore version uses some sort of composite (plastic, nylon) for the roller so after a few years, they started breaking apart. After replacing the old, disintegrated part, the door opens and closes better tha it ever did.  Also, this support comes with a steel roller so it won't break down.
