Lockdown Golden Rod Dehumidifier

3.9/5 Best Safe Score (how we score)

I rank this plug-in heated rod first: it sits low in the safe and warms the air slightly so it circulates and stays above the dew point. Lockdown says it is made in the USA, vermiculite filled and covered by a lifetime warranty, in 12, 18, 24 and 36 inch lengths.

Who it's for

  • Best overall rod in Best Dehumidifier for Gun Safe – 3 Picks Sized by Cubic Feet: For a long-gun or full-size safe with a cord pass-through that sits somewhere damp, like a garage or basement; it adds heat rather than pulling water out, so pair it with a desiccant in very humid climates, and it cannot work in a safe with no way to plug in.

What we like

  • Run-and-forget heated rod; several owners report 10 to 20 years of 24/7 use
  • Four lengths (12 to 36 in) so it can be sized to the safe
  • Made in the USA with a lifetime warranty, per Lockdown

What to know first

  • Needs a power outlet or cord pass-through, and the bare rod gets hot to the touch, so keep polymer and ammo off it
  • Warms the air rather than removing moisture, so owners in very humid garages add desiccant

  • Set-and-forget, with nothing to recharge
  • Keeps an unheated garage safe above the dew point without drying out stocks
