From our introduction of high-tech synthetic fibers for heat resistance, to setting up a working arborist rope-making machine at TCI, we have always embraced new arborist rope fiber technologies and have been the first manufacturer to incorporate them in arborist rope and cable products when they provide the best customer value.
