The SP23 is classified as a Standard Size safe - fitting up to 23 long guns in its interior. Like all Browning ProSteel gun safes, it is designed to take up wall space instead of floor space, projecting a mere 20" from front to back, while still providing 20 cubic feet of interior storage. At a height of 58", it will fit underneath shelving in your garage or in your "man cave". The smaller size of the SP23 makes it perfect for keeping home defense rifles or shotguns accessible, but secure, in your bedroom
