The Mopeka Tank Halo
The Mopeka Tank Halo is a small rubber ring that quickly attaches to the bottom of the most common 20, 30, or 40lb DOT propane tanks. This provides protection against grime, rust rings, and other dings to your patio, grill, or car during tank transport.
The Halo fits easily but is just snug enough to not fall off when transporting.
When combined with a Mopeka Pro Check sensor, it can also significantly increase your sensor's wireless range by providing just enough of a gap between the steel tank and ground for the radio waves to exit. You could see as much as 2x to 3x increased range in these cases.
