They are ideal for flag halyards, dinghy outhaul block, cunningham, leech lines and any other small diameter line application.

        I build garden railroad operations. Mine structures, logging operations, and overhead cranes require blocks in order to be made dynamic. The RF13101-2 fits the bill to a "T".
