Bolts and hangers

placing and replacing it is the job of crag managers and people with appropriate training, because a poorly placed bolt will endanger everyone who climbs after you. Choose the material according to the environment — in coastal and humid areas, corrosion works faster than is visible on the surface. Before climbing, assess every fixed point by eye and hand: do not treat a wobbly, cracked, or heavily corroded bolt as protection and skip the route instead.
