Question: This shows left-side hinges. Can the door-hinge be reversed to become right-sided? Or can the unit be installed upside down and become right-hinged?
Document: I did quite a bit of research before buying this gun cabinet. I wanted a way to store my shotgun safely out of reach of kids and casual thieves but rapidly accessible to me if needed.The main problem with the item I received was that the locking mechanism didn't work. It basically didn't open. After many tries in different positions, I finally got it open once by opening it door-side-down. After that, I was never able to open it again.
I'm delighted, but please be sure to check the length of your gun carefully before ordering this little steel case. I say "little", because it will hold only two short shotguns like mine! But that's precisely what lets it fit behind a bedroom door or in one's closet!
I called V-Line customer support, who answered the phone right away and was very responsive, but couldn't help me solve the problem and determined that it must be either defective or damaged in transit. There was no visible damage to the packaging or cabinet. I sent it back to Amazon, which has a great no-hassel return policy.
Great Case!! Performs as advertsied. I hung mine in my closet on the back-side of some shelving, and at first glance it looks like a breaker box. For me - with a family full of kids, it is the perfect balance between quick access and security. It holds the 870 just fine.
I think it is not secure enough for its intended purpose. When I was fiddling with the door trying to get the lock to open, I could pry a corner slightly open with my fingers, without really trying very hard. I am sure that I could break into this cabinet if I wanted with either my bare hands and a little muscle or with some simple leverage like a screwdriver or a knife. No real tools required.
This case was just right to discretely and securely store a tactical shotgun behind the curtain in the master bedroom, but still allowed quick and easy access. The mechanical combination lock can be opened in the dark by touch in seconds (I don't think you'll want or need to use their 2 key locks). The case seems very well made and it was packaged properly for shipping so there were no dents. It was very easy to mount on the wall and to reset the combination.
You can have this thing open in 5 seconds flat.The steel is heavy enough for a box of this size. It's not overly heavy, but the steel is not the weak point. The combination lock by itself leaves the box pretty prone to an attack with a pry bar. It's best to install this in a way that anyone who wanted to pry it open couldn't easily get leverage, that is, put the side that opens close to a wall or something.
The mechanical key code functionality works effortlessly. The case itself weighs only about 25 pounds so it may not work well as a theft deterrent but I purchased it mainly for the purpose of keeping it safely away from my little one and any curious guests which I think it does superbly.Update:  I added a Tactical Flashlight to the side of the Shotgun and the Safe still closes. The fit becomes snug with the flashlight on but it closes with minimal additional effort as it pushes a little on the padding of the safe.
While not as sturdy as a full sized safe might be, this box will discourage access for most unauthorized users. Be aware that it is designed for a tactical shotgun, and accordingly, the box is not long enough to accommodate shotguns with barrels longer than about 18".
Well I guess Pranav G and I had a communication problem....no kidding. I hung up. Received an email back from Amazon to return the large safe (at their cost). Hey Amazon....would it be easier to just give me the default combination??? Searched &#34;google&#34; for about 15 minutes, found the default combination, opened the safe and the keys that Pranav G told me did not exist were locked in the safe.
Answer: no
