3 Days Ago
Im not saying how great it is. Im just saying it looks great to me. I haven't used one. Charlotte has bigger trees than Detroit, and I am guessing bigger canopies than the Pacific North west. Scotty runs a crane all day everyday. I only run a crane once every few months and one of my crane guys makes me use his shitty slings (with no clevises).
If done correctly those shackles are stronger than the rope itself is. It is far superior than a knot. There is, from what I understand centuries of use behind this configuration in situations with pretty serious consequences if there is failure. So I think there is a lot of historical knowledge on this technique that we have to work with. Both of us should be pretty good at inspecting and monitoring the health of rope. Yes maybe there might be abrasion issues, but people do chock slings without clevises all the time. But maybe like JOMO said they are hard for grounds to undo or they will get tangled up in the canopy. They also won't smack you in the teeth. Are you worried that the piece would fall out? That it wouldn't choke or the knot would pass throughout the eye? It seems equally likely that someone doesn't tighten the clevis screw properly as set the knot properly. Both require a bit of focus and awareness.
