  4. INSTALLATION TWS Units are to be used on new curb ramp locations. TWS Panels are equipped with ½’ x1 ½” heavy duty steel bolts (fasteners) protruding ½” from panel body. The bolts (fasteners) are secured into corrosion resident concrete inserts. This ensures that the bolts (fasteners) are securely embedded 2” into the concrete.
