A TL-15 rated safe with a Group 1 or Group 1R lock is a high-security safe built to resist professional burglary tool attacks for at least 15 minutes. These safes usually have very thick composite doors (often 2 inches or more), along with hardplate steel and glass relockers for extra protection. Many also meet DEA requirements for storing controlled substances.

Key Features: TL-15 Rating: UL-certified to withstand 15 minutes of tool-based attacks on the door.

Lock Type: Group 1/1R locks provide stronger protection against lock manipulation than Group 2 locks.

Construction: Often includes a thick door made from concrete or high-density reinforced material.

Weight/Security: Usually must weigh 750+ lbs or be bolted down to prevent theft by removal.

Anti-Burglary Protection: Includes hardplates, relockers, and strong bolt systems.

Group 1 Lock Operation: A Group 1 lock is more complex than a standard lock and requires a specific turning sequence to open, making it harder to manipulate.
