Protect your regulator from damage in the event your tank gets knocked over. A Gauge Cage is cheap insurance that can help save you a costly regulator replacement.
CO2 and Nitrogen tanks, especially the 5lb size most brewers use, are notoriously wobbly and easy to knock over once the regulator is mounted on them. This handy Gauge Cage helps protect the gauges themselves, as well as the fragile points where they thread into the regulator body, from damage in case of a fall.
Price if for cage only. Gauge not included.
