FAQs

What does level 6 security mean?

Liberty Safe uses a 10-level security ranking system based on steel thickness, door type, lock features, and third-party verification. Level 6 security offers superior protection against forced entry with enhanced locking bars, making it ideal for homes that are unoccupied for extended periods.

Does the Colonial Pro Flex® safe come with internal storage?

Yes. The Colonial Pro Flex™ safe comes equipped with our modular Pro Flex® interior tracking grid. Unlike standard shelves that only move vertically, this system allows you to configure your shelving layout multidirectionally (both left-to-right and up-and-down) to organize long guns alongside smaller valuables. The safe also features a factory-installed interior door panel.

What is the difference between the standard and Pro Flex interior?

Standard shelving uses fixed brackets and a center divider, allowing shelves to adjust vertically. The Pro Flex interior is more adjustable and includes a dedicated zone for mounting compatible storage accessories.

What accessories are compatible with the Colonial Pro Flex® safe?

The Colonial Pro Flex® safe is compatible with our three-drawer Jewelry Box, automatic Watch Winder, and Document Drawer, which mount directly to the heavy-duty tracking system.

Why does the Pro Flex interior have a lower long-gun capacity than the Standard?

The accessory-mounting tracking system slightly reduces total long-gun capacity, ensuring your hand-held valuables remain neatly organized and within easy reach.

• Colonial 23 Pro Flex: Holds up to 21 long guns (vs. 25 Standard).
• Colonial 30 Pro Flex: Holds up to 25 long guns (vs. 30 Standard).
• Colonial 35 Pro Flex: Holds up to 33 long guns (vs. 48 Standard).
• Colonial 50 Pro Flex: Holds up to 45 long guns (vs. 50 Standard).
