Basis for Weight Rating of Trailer Safety Chain

Question:

Do you have a question about part # 337B03822SC? What is basis for claiming 3/8 inch Grade 30 chain 2700 lb WWL is suitable for trailers up to 10Klb? Normally I see safety chain graded as Grade 70 with size chosen with WLL around 3/4 max weight of trailer.

I'm not quite sure what you mean by "do you have a question" although I can tell you the information about the 10,000 lb max trailer weight rating of the Buyers Products 3/8" x 22" Class 4 Trailer Safety Chain w/ 1" Slip Hook - 30 Proof # 337B03822SC comes directly from the manufacturer. They are the ones who test their products and create the weight ratings.
