I'm looking for information regarding wear on my ATC.
The break hand side of the ATC is rounded from the rope running around it, but on the other side a square edge is being created by the rope running straight out of it. This doesn't look like a problem unless the rope was reversed, e.g. use the opposite side for the break, or on rappel, where one strand gets the round edge and the other gets the square edge.
Any idea when it should be retired?
