Clean the inside of the cabinet door along the edge where you will glue the cabinet stops. Use a little rubbing alcohol on a paper towel to remove any grease or soil.
Look at the inside of your cabinet door to see where it hits the base of the cabinet first. Although ideally the door should hit the cabinet base flatly, doors often warp slightly over time.

Peel the paper from the back of the stop. Press the soft stop in place on the inside edge of your cabinet door. Press it firmly for 30 seconds.
