Question: Assuming the pin is within its rated capacity, what is the D/d for a nylon webbing (flat) sling to achieve full basket capacity?
Answer: There are no D/d reductions for nylon webbing. If the pin can support the load of the basket hitch it will be fine. The only concern we have with flat web slings is spatial. The webbing must be able to fully spread, allowing it to use all the material to attain its full capacity.
