The Liberty Franklin 40 is the most popular model in the Franklin Series, offering an ideal balance of premium security, expanded storage capacity, and advanced fire protection. Designed for firearm owners with growing collections, the Franklin 40 delivers upgraded protection with a choice of Standard, Pro Flex, or Signature interior configurations, without requiring the footprint of a widebody safe.
Built with a rugged 11-gauge steel body, Liberty's upgraded DX-90 Monster Mech™ locking system, and 13 Solid State™ locking bars, the Franklin 40 provides exceptional defense against pry attacks, forced-entry attempts, and unauthorized access.
Featuring 110 minutes of Cool Box™ fire protection at 1200°F, the Franklin 40 helps safeguard firearms, important documents, valuables, and family heirlooms while providing the premium features, interior flexibility, and American-made craftsmanship that define Liberty's Level 7 security lineup.
Configure your Franklin with the interior that best fits your collection and the way you want to organize it. Choose Standard for traditional upholstered storage, upgrade to Pro Flex for modular organization through the Pro Flex accessory system, or select Signature for the same accessory-system flexibility with premium two-tone faux-leather styling.
The Franklin Standard interior provides a fully upholstered, traditional safe interior designed for straightforward firearm, document, and valuables storage. Adjustable shelving gives you the flexibility to organize the interior around your collection while maintaining the classic finished appearance expected from the Franklin Series.
The Standard interior offers a traditional upholstered storage layout for customers who want practical organization without moving to one of Franklin's upgraded interior systems.
Adjustable shelving allows the available space to be arranged around firearms, documents, jewelry, collectibles, electronics, family heirlooms, and other valuables.
Standard is the included Franklin interior and provides the essential storage flexibility many owners need. Customers looking for greater modular organization or more premium interior styling can upgrade to Pro Flex or Signature.
The Franklin Pro Flex Interior Upgrade provides adaptable modular organization and includes Liberty's Pro Flex accessory system. Adjustable interior components give you greater control over how you organize firearms, documents, jewelry, watches, collectibles, and other valuables.
Rather than limiting you to a single fixed interior arrangement, the Pro Flex interior is designed around adaptable storage. Adjustable shelving and firearm-storage components allow the interior to be configured around the combination of items you actually need to protect.
That flexibility is especially useful when your storage needs change over time. Shelving and storage areas can be reorganized as your collection changes, allowing the same safe to accommodate different combinations of firearms, documents, valuables, collectibles, and personal belongings.
The Pro Flex system can be configured for traditional firearm storage, valuables-focused organization, or a combination of both. The adjustable interior provides dedicated space for long guns while preserving useful shelving for smaller valuables and other protected items.
The Empty, Organized, and Loaded images above illustrate how the same Franklin Pro Flex interior can evolve from a flexible starting configuration into a fully utilized storage system.
The Pro Flex Interior Upgrade includes Liberty’s Pro Flex accessory-mounting system. See the compatibility and size guide below for available accessory locations.
The Franklin Signature Interior Upgrade combines the flexibility of Liberty's Pro Flex accessory system with premium two-tone faux-leather upholstery, including a diamond-stitched backwall and coordinating diamond-stitched deluxe door storage panel. It provides elevated organization for firearms, jewelry, documents, collectibles, electronics, heirlooms, and other valuables.
The Signature Interior Upgrade is built on the same Pro Flex accessory system as the Pro Flex Interior Upgrade, then elevates it with premium two-tone faux-leather upholstery, a diamond-stitched backwall, and a coordinating diamond-stitched deluxe door storage panel.
Adjustable shelving and firearm-storage areas allow the interior to accommodate different combinations of long guns, documents, jewelry, collectibles, electronics, heirlooms, and other valuables.
Signature isn't simply about appearance. The interior can be arranged around the items you actually need to protect, allowing you to balance firearm storage with shelving and organized space for other valuables.
The Empty, Organized, and Loaded images above demonstrate how the same Franklin Signature interior can progress from an open, flexible configuration to a fully utilized storage system.
The Signature Interior Upgrade includes the same Pro Flex accessory-mounting system, allowing compatible Pro Flex accessories to be added while retaining Signature’s premium styling.
Standard is included in the base price. Pro Flex and Signature are available as interior upgrades.
Pro Flex is Liberty’s modular accessory-mounting system—not simply the name of an interior package. The system is included with both the Pro Flex Interior Upgrade and the Signature Interior Upgrade.
Compatible Pro Flex accessories install in the dedicated left-hand accessory section, which Liberty calls Zone A. Available accessories include the watch winder, jewelry storage, and document storage accessories.
Franklin 29, 40, and 50 models correspond to the 30-inch, 36-inch, and 42-inch width classes shown below. The guide identifies the left-hand accessory section—Zone A—where compatible Pro Flex accessories are installed.
Pro Flex accessories work with both Pro Flex and Signature Interior Upgrades. They do not fit the Standard Flex Interior. Accessory compatibility varies by safe model, size, and individual accessory.
Make a statement with Liberty's distinctive Glacial Steel finish. Available on select Franklin safes, this modern metallic finish pairs Franklin's Level 7 security and 110-minute fire protection with your choice of available interior configurations.
If you'd prefer a mechanical lock, please specify "MECHANICAL LOCK" in the notes section during checkout.
