UL Rated Safe Lock Mechanisms
Mechanical Combination (Dial) Safe Locks
- Group 2– These locks offer the most basic level of dial lock security and are designed to resist semi-skilled manipulation attempts for less than two hours. These locks are best suited for use on RSC, B, and C rated safes.
- Group 2M– These locks offer resistance to manipulation carried out by a skilled expert for up to two hours. This category provides a good “mid-range” lock to place on a TL-15 or TL-30 safe.
- Group 1– These locks are rated to withstand 20 hours of expert manipulation, but they are susceptible to x-ray, allowing them to be opened in a shorter time. These locks are expensive and are used on higher priced safes that are rated TL-30 and higher.
- Group 1R– These locks are rated the same as Group 1, but have an added x-ray resistant feature.
Electronic Keypad Safe Locks
- Type 1– These locks are rated to withstand expert manipulation for 20 hours, plus additional specifications outlined below.
- Type 1F– These locks are similar to Type 1, but also conform to U.S. Federal Specification FF-L-2740. These locks are made for use by Federal Government Agencies.

Explosion Hazard Test
Fire Impact Test
During a fire a building’s structural integrity may become compromised due to the flames and high temperatures. Thats why the Fire Impact Test was developed. This optional test simulates the effects of a safe dropping through the collapsing floors of a three story building, and is conducted immediately after the Explosion Hazard Test. Within, two minutes of being removed from the furnace, the safe is hoisted 30 feet high and dropped onto a pile of bricks which are resting on a solid concrete slab. The safe is inspected for damage and, if it appears intact, it is returned to the furnace for re heating. After, a predetermined amount of time the furnace is turned off, and the safe is allowed to cool. Once, cooled, the safe is removed and carefully examined for damage and heat transmission.
