This rubber stop fits several series of Avantco equipment, working to protect it from damage. Some equipment will use it as a door stopper, or a spacer on the back of the unit to provide proper clearance against a wall. On ice cream dipping cabinets, it prevents the lid from hitting the unit when lifted. On milk coolers, it installs on the inside of the door so that objects do not run into it while the door is flipped down. If the rubber stopper on your unit is torn or worn down, this one can be used to replace the original part quickly and easily!
