The Americans with Disabilities Act. This landmark legislation provides for stiff civil penalties for any business, workplace, or public institution that fails to provide appropriate access to disabled persons. It means much more than just ramps! In many cases, door knobs are non-compliant because they are difficult for people with limited hand strength or dexterity to operate. Professional locksmiths can advise you on ADA compliance issues that relate to the door hardware at your business or workplace.
