The concave collar rests between the draft tower and the main body of the tower shank. This black concave collar pairs perfectly with the NukaTap Stealth Bomber faucet without the need to purchase a whole new shank. Or add some flair to your existing setup by mixing and matching black and stainless steel.
Handle this part with care, as scratches will show up more clearly compared to the stainless versions.
