Surprised you were looking at his rod; figured you would be lusting over his whinnies.
Any way, Glad it works for him; I just never heard of them till now.
You must live a very protected life! He he! I have used Golden rods for years and I know many people who use light bulbs in there safes with good results too. Many welders keep their welding rods in boxes with small watt light bulbs to keep it dry so it will work right too. Golden rods can claim whatever they want but all they are is low wattage heaters. I have a friend who has used a left over aquarium heater from his fish collecting days for years in his safe.
Most all good quality safes have holes in them for leads to Golden rods or whatever and that does not cause any reduction in the fire ratings at all. They are usually very hard to spot and before setting a safe you should find just where it is and work the wire out and tape it to the front of the safe before setting the safe where you want it. Then it takes a snap on plug for an electrical connection and you are on the road/
I have gone through about 5 or 10 dehumidifiers over the years and never had one that last over two years while running 24 hours a day. Even the timed ones that run for limited hours fail to hold up long. So I am giving timed and thermostatically controlled air conditioning a try now. I use dry electric heaters in the winter and that works just fine so far. They have a naturally dry heat and save a few bucks keeping the place in the 50's at worst temp wise. I also have bags of desiccant a member here was selling a few years back in each safe.
Oh a word to the wise Golden Rods are supposed to be sized to the safe so keep in mind if you have a big safe you need a larger rod to work right. If the power goes out for a week like I had happen a couple of years ago just keep out of the room and hope for the best I guess. I use Balistoll and the above efforts and I had no trouble over the outage time. I also stored using Balistoll and wrapped in plastic trash bags, doubled and sealed with tape inside a cardboard shipping box for almost 5 years in a leaky and unheated attic with no troubles. I would say that was just about as long as that would work as things were getting ready to rust about then I think. Many different ways to get the job done and I have learned a bit off this thread too! Bill
