The Miller R10CN-TB-BDP/UGN Revolution Construction Harness was engineered to meet the demands and needs of working at heights on a construction site. This full-body construction harness uses the same great features as the original Revolution but with heavier duty webbing that is almost twice as strong than the standards require. When you are working hard on at a construction site, this construction harness works just as hard. R-10CN-TB-BDP/UGN HARNESS
