Product review (5 stars): Perfect for 110.86873100 dryer and others.
Perfect fit for my kenmore 110.86873100 electric dryer. Several different  spring type  latches are included. Instruction say to select one with the same number stamped on it or match the color of the spring. My original was unmarked and not one of the provided colors. The numbers on the latch spring is the thickness of the spring steel. The 20 is about .020", 22 is .022" and a thicker spring is  a tighter  latch. I could see mine resembled the thinest spring. Then i measured the thickness with a caliper to confirm and then realized latch number is spring thickness in thousandths of inch and the only difference between the provided parts.
