Question: Can a security cable be used with this safe?
Document: Robust safety with no batteries needed. Once installed on an immovable shelf or dresser, this is a great place to secure firearms out of the reach of those in danger. Opens quickly using the mechanical buttons you can program with 1080 unique combinations. This American-made safe has the same locking mechanism used on doors in hospitals, police stations, and other high security locations. Foolproof safety for firearms and other valuables.
I love this Item. The only reasons it did not get five stars is if you try to register the lock for warranty purposes Simplex does not recognize that their locks are being used and therefore the product is not listed on their site. The simplex lock is outstanding. The only other thing is this box should be configured with a cable allowing tethering.
)You need a heavy table to put this on, or just put it under the bed. (No holes for a cable, though, if you want to tie it to the bedframe...get out your drill. )Comes with a paper template for bolting it onto a surface. I ordered a heavy-duty nightstand for this purpose, but the safe is so heavy, it deters casual criminals and mischievous types just by the weight (and bulk) alone. Serious criminals will take it (by smashing the nightstand, if necessary), whether bolted on or not.
This was given to me as a Christmas present. I daily CCW and grew up around and learned an early deep respect for firearms so I wasn't crazy about the idea, or used to having a safe. The construction of the box itself is top notch, this is bolted under a cabinet next to my back door and holds my daily carry piece as I leave every morning and after 6 months of daily use the lock self destructed. It was early and at first I thought I had forgotten my push-button code.
Very sturdy and secure safe. However, the safe appears to be upside down with the door opening to the right instead of the left as pictured. The push buttons took a little getting used too. I like the idea of: heavy duty steel shell and door, a dead bolt lock, concealed hinge, recessed door, and no batteries. I only rated it 4 stars primarily because it does not come with any mounting instructions. However, it does come with 4 pre-drilled holes on the bottom, with plastic knockouts.
You can change the combination. This box gives me fast access, and keeps my gun safe from kids and visitors.I recommend practicing:  access of gun, chambering a round, and taking your best stance (for your room's security situation), all in one session--from a lying position, under covers (assuming it's in your bedroom). You want the confidence that comes with knowing you won't fumble the combination when adrenaline kicks in. Do this regularly. The buttons work very smoothly, but a nervous hand could slip off of them, since they aren't recessed.
That was when I made the decision to go mechanical. This safe is SOLID. The Mechanical lock is fantastic. the size is good enough for my 10mm, 9mm and my tactical flashlight. with lots of room to spare.I would suggest bolting it down or securing it to something as you down want it to walk away. I purchased a master lock python here on Amazon. I used the mounting holes in the safe and stringed it around the bed frame. It should add an additional hassle should someone attempt to take the safe.Update 12/29/2012After several months of ownership the safe works great, as expected.
It's obvious, the Fort Knox handgun safe is built with quality, strength, and security in mind. I want to know that when children are in the house, I don't have to worry about their safety. It's also important that my wife and I have immediate access to a weapon if the need ever arises. In addition to securing my pistol, there's enough room to hold the ammunition I keep on hand, in the house.The safe arrived on time, well packed to protect it during shipping. After looking through the instructions, I was able to change the combination to the lock.
Update: 8-30-13Taking two stars from my review. Why you might ask? The Product has been good but the issue comes with the lock and it's security. Also, I could not verify that this version of the safe has been UL Rated so could be a issue in California. ThisFort Knox FTK-PB Pistol Box Handgun Safemodel by Fort Knox has. The safe seems to be using a Kaba 9600 lock and their in lye's the problem. It is a five digit lock and a quick search found a article on how to brute force attack the combination and all possible combinations listed.
I rate this a five for security and quality in metal thickness and welding but reduced that to a two for quality control checking and customer service.The door does not open as shown in the picture, it opens just opposite as it shows,the other side opens. I had to change how I positioned it in my vehicle. Mine also was missing the Fort Knox nameplate shown on the box and I even ordered mine direct from the company. If you spent 3000 to 6000 dollars for a safe from this company and you expect it to open on the right side and when you get it delivered it opens on the left side you'll be pissed.
