Guide to Hollon Safes Locks

Want to learn more about the best lock option for Hollon Safes? Our Guide to Hollon Safes Locks will teach you everything you need to know about the available lock options, so you can make an informed decision when shopping for your new Hollon Safe.


There are two lock types available for safes:  Mechanical Dial Locks and Electronic Locks.  Within each type, there are subtypes that offer different features and security ratings. 


When shopping for a safe, you will want to look for one with a UL rating.   UL stands for Underwriters Laboratories, which a global independent safety science company.  This organization tests the latest products and technologies for safety and compliance.  A lock that is UL Listed means it has been tested by UL to nationally recognized safety and sustainability standards.  This is the standard insurance companies go by.




Sargent and Greenleaf Dial Lock


Group 1(R): These locks are resistant for up to twenty hours of skilled manipulation attacks as defined by Underwriters Laboratories. These locks are recommended for TL-30×6 safes and higher. 

**Please note that these locks are not stocked by Hollon Safe and must be special ordered.**


Group 2: These locks are the most common locks put on safes and perform well in most applications. They are generally used on B and C Rated safes and most RSC containers. They are not recommended for TL-15, TL-30, and TL-30×6 safes.


Group 2M: These locks are resistant up to two hours of manipulation as defined by Underwriters Laboratories. These locks are best used on TL-15, TL-30, and TL-30×6 safes.

Sargent and Greenleaf Spartan Electronic Lock


Type 1: These locks are resistant to expert manipulation and are also radiological resistant. They are also non-volatile meaning that they will retain your code even if the battery(s) lose all power. Type 1 locks can be used on almost any safe starting with simple B Rate units all the way up to TL rated safes.  Most of the electronic locks stocked by Hollon Safe are Type 1.


The following are electronic locks available from Hollon Safes.  Each electronic lock option requires a 9-volt alkaline battery.  Some Hollon Safes models come standard with the S&G Spartan E-Lock.  Optional electronic lock upgrades are available for an additional cost, and can be selected using the drop down menu located towards the top of the safe’s product page.
