What is the capacity reduction for a web sling used in a choker hitch?

RIG-005 · Rigging
A web sling used in a choker hitch has a capacity reduction of 25%, meaning it retains only 75% of its rated capacity.
When a synthetic web sling is rigged in a choker hitch configuration, the sling capacity is reduced to 75% of its straight vertical lift rating. This 25% reduction occurs because the choker creates a compression point where the sling wraps back on itself, concentrating stress and reducing the effective bearing surface of the webbing.
Reference: ASME B30.9 Slings standard
Remember: "Choker Chokes a Quarter" - choker hitch reduces web sling capacity by 25%, leaving 75%
