If you're a gun enthusiast, then rust is one of your worst enemies. Eliminate moisture problem in your gun safe with Dri-Rod's 18" Electrical Dehumidifier Rod. It creates a stable environment inside the safe, reducing changes in temperature and keeps air circulating around the enclosure, eliminating musty smells and dampness. Place at the bottom of your shelf in a horizontal position or mount to the side of your wall with the supplied mounting brackets and screws.

It comes with the plug detached, so you can run the cord through the hole in the back of the safe. It is also supplied with detachable feet with screw detents, which lets you install the unit in your dry wall.
