The locks used are S & G (Sargent & Greenleaf), there are four holes on bottom plate, I do not think they are designed for stud mounting but I could be wrong, if the hinges were cut, the locking mechanism has four large steel bars that lock into each side so removing the hinges does not allow access to the interior of the safe. I have decided on there model #2722. It weights
580 lbs. I am upgrading to 7 gauge steel. It has a deluxe interior. Normal price is $947 but a current sale as it going for $775. It is H60", W27", D22.5". Capacity for 25 guns. I do not own that many guns NOW but do have lots of ammo I want locked up. I just find it unfortunate that a company that does not advertise in gun magazines does not get the attention but I know that is what advertising dollars are for. They make rock solid safes and I just want others here on AR15.com to know about them. Shipping for me is not a factor since they are just ten minutes away. You could call for shipping rates. I know it must not be cheap. Just a plug for a good company for they guys and gals here. Sorry, I am off my soap box now.
