Hornady 95903 Dehumidifier Rod 12" Black Polymer

The Hornady 95903 Dehumidifier Rod is a maintenance-free humidity control solution for gun safes, cabinets, and small enclosures. The 12-inch rod gently warms the air inside your safe enough to raise the internal temperature slightly above the ambient room temperature. That temperature differential shifts the condensation point to the outside of the enclosure, keeping moisture from forming on metal surfaces and protecting stored firearms, optics, and other valuables from rust and corrosion.
