This powder-coated steel gauge guard protects gauges on Taprite, NADS, and Brewer's Edge regulators. Does not fit other brands of regulators. Fits firmly and does not slip like wire cage models. Fits both our D02 Gas Regulator, D22 Twin Gas Regulator and D93 Brewer's Edge Paintball Tank Regulator. Ideal for those who move their kegging system around.
