Hi Teri, thanks for the question.
I'm not exactly sure what you mean by a normal refrigerator/freezer (meaning residential or commercial?), but in regards to the Beverage Air 2 Door Dual Temperature fridge/freezer combo you get a heavy duty commercial unit. The stainless steel interior and exterior is extremely durable, the door handles are anti-microbial, the doors are field reversible, and yes the doors do lock. Each door has a keyed lock on it so your food is safe.
We have a few different refrigerator/freezer combo units that we sell. If you'd like a little more detail on our offering, and assistance in picking out the right unit for your establishment, don't hesitate to give a member of our Tundra Restaurant Supply team a call at 1-888-388-6372.
