Abstract: An apparatus and method for using a single radial TWS product for a variety of applications is disclosed. Radial TWS products are used for intersections and the like. Often, different applications require radial TWS products of varying dimensions. The present invention includes a radial TWS product, having domes on its upper surface, which are ADAAG compliant. Markings are placed on the bottom surface, which indicate the appropriate places where the TWS product can be cut to achieve a variety of effective radii. These markings are positioned such that, after being cut, the resulting radial TWS product continues to meet the ADAAG required center-to-center spacing between domes of adjacent cut TWS products. In some embodiments, anchor members are used in conjunction with the TWS product to allow simple replacement.

Abstract: A replaceable, wet-set tactile warning surface unit having a body defining an upper surface and a lower surface, the body defining a series of raised projections on its upper surface, and defining a plurality of spaced through-holes from the top to the bottom surface, in which the raised projections are spaced from one another and the through-holes are located between projections. An anchor member such as a threaded insert is coupled to the bottom surface of the unit member directly below each of the through-holes by fasteners such as bolts that pass through the through-holes.
