I just splice mine in a basket config to use as a Prussic. They fit through a very large ring to use either in a retrievable (can set from ground) or in a choked config. Just look up a “u-saver”. I think it is from old fart.I girth hitch my Pintos to webbing slings/ loop runners with the spacer in place, I thought that’s the point of making these pulleys with thick soft edges. “ Textile friendly” was how they were advertised anyways.
