Comes with a welded 3/16" nipple, back nut, and plastic collar. It requires a 1" hole for installation. When set in place, the shank will only have about 1 7/8" of length to pass through your wall or fridge door, due to the length of the collar and back nut.
Installation note: On a fridge there is generally no coolant lines running through the door but please check to see there are no lines connecting the door and the rest of the refrigerator. To test for coolant lines on a freezer start with a warm freezer then plug the unit in with the lid open. You should be able to see the lines form condensation on the inside of the freezer where there are lines running. Please still use caution when drilling.
