Assembled and and spliced by an ATRAES factory trained and certified rope splicer this fiddle block is ideal for pretensioning lowering lines or lifting heavy objects.

The ATRAES fiddle block will give you a lifting/ pulling raio of 5:1, so pulling with a force of 100kg results in 500kg of lift. The ISC Double Rescue Hauler has a built in cam so between lifts the load won't run. The cam can be quickly released if needed by tugging the release line.
