Security measures how well a lock or deadbolt can withstand impact, whether from a possible intruder or extreme weather conditions. Durability measures how well a lock or deadbolt functions after repeated, long-term use. It also measures how well a lock or deadbolt operates with excessive weight on the door — such as a hanging purse. Finish measures how well your door hardware can endure under a wide variety of conditions over the span of the product’s life. Severe weather events and other factors, such as sun exposure, humidity, saltwater, dew and even the oils in our hands, can cause damage to entire structures and cause the finish of a lock or deadbolt to discolor or corrode.
Security = Safety
Durability = Functionality
Finish = Withstanding the Elements
These ratings indicate how well your product performed during testing in each category, and can help you determine which combination of ratings is the best fit for your specific hardware needs.
