	** NOTE TO SPECIFIER ** Access Products Inc.; Articulating sidewalk joint. . This section is based on the products of Access Products Inc., which is located at: 241 Main St. Suite 100 Buffalo, NY 14203 Toll Free Tel: 888-679-4022 Tel: 716-474-2462 Fax: 877-679-4022 Email: request info Web: accessworldproducts.com [ Click Here ] for additional information. Access Products serves the needs of municipalities and building and facility owners. We manufacture, distribute, and install durable building products that provide for the safe and efficient movement of people on sidewalks, stairways, and bridges. Our products improve the quality of transportation infrastructure for pedestrians and the disabled, and ensure the safe egress of large numbers of people from public facilities. For the transportation infrastructure market Access Products manufactures Access Tile™ Tactile Systems and the TripStop™ Articulating Sidewalk Joint System. Access Tile is a tactile detectable warning surface that is designed to provide safe passage for pedestrians and the disabled on sidewalk curb ramps, pedestrian walkways, transit platforms and pedestrian bridges. Access Tile is compliant with the United States Americans with Disabilities Act (ADA) and international legislation for the improvement of disabled accessibility on public rights of way and transit systems. TripStop is an articulating sidewalk joint that eliminates trip hazards on concrete sidewalks due to sidewalk slab displacement from tree root invasion, expansive soil movement or thermal expansion. TripStop enables governments to maintain safety compliance for sidewalks and pedestrian walkways to reduce the risk of trips and falls and the potential for personal injuries that might result. Access Products produces Ecoglo photo luminescent exit path marking systems for large-scale buildings including arenas, stadiums, performing arts centers, high-rise office buildings, condominiums, and large-scale industrial facilities. Ecoglo™ helps prevents trips and falls and also acts a supplementary fail-safe emergency lighting and exit path markings system for exit stairways, handrails and aisles in public buildings and industrial facilities. Ecoglo meets the requirements of the International Building Code (2007 IBC Supplement, Section 1027 Exit Path Markings). Access Products strives to provide building products to global markets that not only enable a safer built environment but also meet the demand for environmental sensitivity. .
