ADA Truncated Dome Bump Pads

The Americans with Disabilities Act or the ADA was enacted to safeguard the rights of disabled individuals. This act mandates specific accessibility requirements for building and other venues that are open to the public for any reason to ensure that handicapped people can enter, travel through and exit them with ease. One stipulation it includes is the installation of Detectable Warning Surfaces as specified in the ADA Accessibility Guidelines of the ADAAG.

ADA Pads are the only detectable warnings permitted by the ADAAG since they are the most effective choice.
