With their durable materials, commercial door knobs are built to survive the rigors of use in heavy traffic areas making them ideal for a wide range of businesses and locations. These high-quality commercial locks are graded by ANSI (American National Standards Institute) for strength and durability for added peace of mind in the purchase.
When shopping for this type of doorknob, you will notice there are two grades. Grade 2 commercial door knobs are meant for use in medium to light traffic areas such as professional buildings, hotel/motel, religious buildings, apartment complexes, or even medium to high traffic residential locations. Grade 1 commercial door knobs are used for heavy-duty applications where hard or continuous use is expected. Hospitals, schools, public buildings, industrial buildings and factories are all places where Grade 1 locks would be needed.
