Rope fitting question

[Bigsnowdog]

I received a long piece of 5/8 Yale Polydyne. I am going to use it to tension trees to fell. No rigging, just tension. I will probably use a truck as the anchor point. Is there some commercial fitting that provides a larger radius than the neck of a hitch ball that would protect the rope? Something I can attach to a piece I put in my receiver hitch?

I am trying to protect the rope, and would make something, but figure someone sells something. I realize a rope block would work, but hate to spend that much money if it does not need block function.

Thank you.
