My father and I want to have a harness and tether system to keep us safe on the corrugated iron roof. We go up there for lights, the air conditioner and cleaning gutters. There seem to be a lot of options available so I figured it would be worth asking if anyone has any suggestions on which is best. We are currently looking at a B-SAFE roofers kit of some sort such as this one. For anchor points we are considering the FrogLink and TempLink but are unsure if these are the best. Any suggestions would be fantastic!
