After much deliberation and general buyer's guilt I pulled the trigger on a Sturdy 4824 with fire liner. I am having them install the reinforced bolt down holes and need help for the anchors I will need and the length of said anchors.
Also anyone using a door organizer? TIA. |

I have been using a lot of Tapcon concrete lags around here. 3/8" lags require a 5/16" pilot. They have a bit more holding power than your typical drive in anchors, and are much easier to remove if you should take the safe away at some point in the future.
You do have to be careful with them to make sure your pilot hole is correct. We have also had some issues with hard rock in the local concrete that can strip the threads and weaken the holding ability. Otherwise they are quick, easy, and effective. There are other companies that offer them as well (like Hilti). |

I think the tapcons that we carry on the truck are 4". You don't really need them that long either, as the maximum holding strength of the bolt is achieved within the first few inches. and can anyone reference the thickness of a sturdy bottom with fire?
I have only seen two of them, and don't recall exactly how they were set up. If they are anything like the others, you will have a void where the bolt will seat against the steel bottom of the safe. There are a few types of safes that have a tube that runs up the bolt hole where you need a longer bolt. Perhaps somebody with a fire lined version will chime in. |

I used the 4" 3/8 tapcon for the first safe mistake was wondering other options etc |

Pretty sure you need 6". I bought anchors and got the 6" thinking "Wow, these will really hold it great", they were the longest I could get at Lowe's/Home Depot.
When the safe came I was surprised to see that the bottom of the safe is really thick. I'm not sure a 4" would have even made it to the concrete. I'd talk to Sturdy and/or wait until the safe arrives so you can measure. I was pretty surprised, I know that. The 6" held great, but I was hoping for more purchase in the concrete. |
| Is there an average thickness for concrete pads and/or concrete basements? House built in early to mid 70's. I believe they told me 5-6 inches at Lowes. I was scared shitless of drilling all the way through it when installing my bolts to bolt down my safe. I used 3/8" x 5" Red Heads which require a minimum embedment of 1.5". I also used a couple Trex deck board as a spacer (approximately 1") per the manufacturers specification to allow air underneath. The anchors and the safe seem to be very well anchored. As I said, I'd rather not royally fuck up my house bolting a damn gun safe down. |
