The GoldenRod GunSaver Dehumidifier is designed to handle humidity from the interior of your safe, locker or cabinet and protects against rust by generating a low level of heat that removes moisture from the air. As the warm air circulates throughout the safe on a continuous basis it eliminates humidity, mildew and condensation, all of which can be dangerous for your firearms collection. All GoldenRod GunSafe Dehumidifiers come with a detachable plug for easier mounting. Check with the details below to see the estimated square footage provided by this critical must have device.
