Southeast Safes
The Lincoln 50 is the largest safe in the current Lincoln lineup, combining maximum Lincoln storage capacity with Level 9 security, two hours of fire protection, and premium interior organization.
Built with a 10-gauge steel body, Level 9 Security, and 2 hours (120 minutes) of Cool Box™ fire protection, it is designed to help protect firearms, important documents, jewelry, family heirlooms, and other valuables against fire and forced-entry attempts.
Security features include 15 Solid State™ locking bars, an advanced drill-resistant hardplate with ball-bearing protection, and dual relockers that engage during forced-entry attempts. The Lincoln 50 is also a UL Residential Security Container (RSC) and California DOJ-approved Firearm Safety Device (FSD).
And now, the Lincoln 50 can be configured with your choice of Standard, Pro Flex, or Signature interior, allowing you to choose the level of storage flexibility and interior finish that best fits your collection.
Configure your Lincoln with the interior that best fits your collection and the way you want to organize it.
The Lincoln Standard interior uses Liberty's traditional 4-in-1 Flex storage system, giving you a versatile upholstered interior that can be arranged around firearms, documents, valuables, and other belongings.
Liberty's 4-in-1 Flex™ interior allows the shelving and firearm-storage areas to be rearranged into four different configurations depending on what you need to store.
The Lincoln 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 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 Lincoln Signature Interior Upgrade pairs the flexibility of Liberty's Pro Flex accessory system with a refined two-tone faux-leather interior, 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 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.
Lincoln 50: The Lincoln 50 corresponds to the 42-inch width class shown below. The guide identifies the dedicated 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.
