Pull out cabinet trays are extremely functional and popular in today's kitchens as well as entertainment centers and other high-end cabinets. Unfortunately, when the cabinet door is not fully opened, the pull out tray can scar the back of the cabinet door. These nifty bumpers attach easily to the drawer corner with an adhesive backing, or mount using #6 x 5/8 screws. The bumper is made of slick and durable UHMW (Ultra High Molecular Weight) plastic. Made in China.
