The Big Dan is a steel autolocking carabiner from ISC that is widely used in tree work for rigging. This carabiner can take a beating compared to aluminum carabiners. A spliced eye in your rigging line makes for an easy attachment point for the Big Dan. Toss in a couple webbing slings and you have a perfect knotless rigging setup.
