The 9000 represents the working load in kilos. The new snatch block can be used with steel or synthetic rope. As long as the steel rope is inspected for fraying after any use, then you shouldn't have any problems. ARB has been using Polymer in their lockers for years, and its shocking as to what kind of abuse this material can take.
