Mine is an older model and I not aware of aN opening. The newer models may offer this option, which is a good item to add a small ventilation fan. I use Damp Rid in mine to collect moisture due to humidity.
No it doesn't. The 17.62" is the depth of the cabinet only.
It's 26 3/4" wide, you would be able to open the door to 80-85 degrees, just short of 90 degree. Which is plenty to access whatever inside. i actually have that same issue, it's between a wall and bumped up agains my desk. I hope this helped.
Yes you can. It also comes extra plastic shelf holder.
No safe is "fire-proof" per say..... there's just different levels of "fire-resistance". This one is rated to hold back 1400 degrees for about 30 minutes before internal temperatures climb. Also, during a fire, a safe near the center of your home would get hotter quicker than one by an exterior wall. How close is your fire department?
19.0 cubic feet is the safe capacity of this product.
