Faucet Shank 3-1/8 in Stainless with Nut and Nipple

Comes with a 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.
