Due to Australian Standard regulations, as part of the Disability Discrimination Act compliance, it is now mandatory to provide Tactile Warning Indicators to stairs, ramps and many other changing conditions. The SureSteel Stainless Steel tactile indicators meet all these requirements and more. Available as a plain back stud or spigot with newly introduced Drill&Lock technology, these tactiles will keep all areas safe. Choose between a carborundum grit or steel rigid top which both achieve the highest level R13 Slip Rating. Plain backed stud requires adhesive for installation, no drilling required. Install the Spigot stud by pre-drilling the substrate with a suitable masonry or wet core drill bit, no glue required for this option.
