According to the Americans with Disabilities Act, handicap-accessible doors must have what type of hardware?

1. Single lever handle hardware

2. Electronic lever hardware

3. Panel-type lever hardware

4. Round-type knob

The correct answer is: Single lever handle hardware

The Americans with Disabilities Act (ADA) specifies that doors in public spaces must be accessible to individuals with disabilities, which includes specific requirements for door hardware. The correct type of hardware is a single lever handle design. This type of handle can be easily operated with one hand without the need for tight grasping, pinching, or twisting of the wrist, which is crucial for individuals with limited hand mobility. In contrast, other types of hardware, such as round knobs, do not meet ADA requirements because they typically require a closed fist to operate, making them less accessible. Electronic lever hardware may not always be appropriate for all situations, particularly if they require additional operations like power or batteries. Panel-type lever hardware can sometimes complicate accessibility, depending on the design, because it may be less intuitive or usable than a single lever. Thus, a single lever handle best conforms to the ADA's intent to provide equal access and ease of use for all individuals.
