The Stein 5:1 Hauler Kit, also known as a Block & Tackle or Fiddle Block, comes supplied fully assembled in a STEIN rope bag, ready for use. The 5:1 Mechanical Advantage means you only need to apply 20 kg of force to lift a 100 kg weight. The 5:1 Hauler Kit includes 25m of 12-strand 13mm rigging line with an average break strength of 2722kg, and two ISC RP064 double pulleys each with a 50kN rating connected with the ISC Iron Wizard and ISC KH212 steel carabiners. A single pull length is up to 5 meters. The locking mechanism uses a STEIN Copious Cool e2e friction cord tied in a Michoacan to capture the load during progress.
