These Braille signs make it easy for everyone to comply with ADA (American with Disabilities Act) laws. Signs are made of high impact styrene (plastic) that can be used indoors and outdoors. All pictograms, borders, lettering, and Braille are raised 1/32" high. Signs come with double sided tape on back for easy installations on any smooth surface, just peal backing off and install. Also, may be installed on rough surfaces, like brick buildings by using epoxy. These are 6" x 9" and available in the following colors: white on black, black on taupe, or white on blue. Some of these signs are commonly used on restroom doors. The Braille lettering is found on the bottom of the sign, right below the text.
