Here are the weirdest hangers I have seen, the Dupla hanger from Bonier found at https://www.bonier.com.br/dupla. They are designed for a climbing rope to be threaded directly into them and the proved to be stronger than the rope. These were donated by Greg Barnes from the ASCA, support their bolting efforts at https://safeclimbing.org/. They seem to be hard in the states to get since they are a Brazilian company.
