Filling growlers can be awkward at times due to the height of the beer faucet from the counter—top. Often there is not enough clearance for the growler jug to fit under the faucet. Our 2—piece growler risers gives you that extra needed room. They are easy to install, with no need to remove the beer lines. Simply unscrew the tower from the counter-top, lift the tower up, place the riser under the tower and then using the supplied hardware reattach the tower.
