  • Commercial Door Operators: A UL 325 2010 Safety Mandate Review

    Most users of commercial garage doors assume that because there are so many options to choose from, that it will be an easy decision to select the exact one needed. However, this assumption is far from true, due to the variation in types of commercial door openers and the tough standards they must meet. The variety of options can make the choice even more confusing. By the end of this learning unit, you will be able to list the different types of commercial door operators available and identify the types of operators for commercial door operators. You will be able to describe the importance of photo eyes and their placement. Finally, you will be able to define the UL 325 Code and its importance. Take the course.
