The Vaultek 20 series is basically a larger version of the VT10i that I had reviewed.
It offers the same great features, such as an awesome 5 digit keypad, many ways of entry, and smartphone compatibility.

Vaultek 20 Series Dimensions
The differentiating factor of this safe is it’s size. The exterior dimensions are 11.5″ wide by 9″ deep, and 2.625″ high.
To make sure your firearm or valuables fit on the inside, it has interior dimensions of 11″ wide b 5.75″ deep, and 2″ high. I would generally recommend drawing a square this size on a piece of cardboard or paper and making sure what you want to fit, will fit in the safe.
The Vaultek 20 series weighs 7.2 pounds.
Vaultek Quality
I am a huge fan of Vaultek. They make some of the best products out there in the market. They work when you need them, and look awesome while doing it.
Conclusion
For more info on this product, I definitely recommend you checking out my in-depth in person review of the Vaultek VT10i, and just keep in mind it is a bit larger.
