What is UL 325?

• A. UL 325 is the safety standard for gate operators and hardware
• B. UL stands for Universal Locking
• C. It only applies to commercial gates
• D. It specifies color requirements for signage

Answer: (A)

UL 325 is a safety standard published by Underwriters Laboratories that sets the performance and testing requirements for power-operated gates and their hardware, including gate operators and safety devices. It defines what features must be present and how they must function to protect people from injury, such as obstacle sensing, automatic reverse or stop on contact, warning devices, and proper installation practices. This standard applies to both residential and commercial gates, not just one sector. It’s important to note that UL stands for Underwriters Laboratories, not Universal Locking, and the standard does not specify signage color requirements.
