The Winchester Safes Dehumidifier protects your valuables from condensation, rust and mildew. By producing small amounts of heated air that circulates throughout interior of your safe, it helps remove moisture from the air. Ideal for humid environments or climates. All Winchester Safes come with a small pre-formed exit for electronics cords on the back of the safe. Safes equipped with Power Docking Systems make this accessory an easy plug-and-play feature to safeguard your gun safe's contents.
