Planning tie-downs

Use enough tie-downs that their combined rating is at least half the cargo weight, and follow the rules that apply to your load and trip.
Put corner protectors under straps at sharp edges.
Match chain, hooks and binder to the same chain size and grade.

Chain and hooks: transport chains and grab hooks.

Why use corner protectors?

They stop sharp edges from cutting straps and spread the strap pressure on the load.
