Chrome plated brass shank comes with a back nut, plastic collar, and a welded 3/16" nipple. Requires a 1" hole saw for installation. Due to the length of the back nut and collar, the total length of the shank will be about 2.5".,,Installation note: On a fridge there are 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.
