6:1 Downhaul System - Harken 29mm Blocks

6:1 Downhaul System, using Harken 29mm blocks.  

This downhaul system is available with a choice of Robline Polytech or the premium Marlow GP78 secondary control line, both of which have a Dyneema® SK78 core and blended Technora®/Polyester cover for durability and grip.  Robline Polytech is a flexible line.  

Primary line is 5mm SK78 Dyneema.

Choose the secondary line type and colour and length that you want, and what rig that you want your system optimised for.  

Please note that if you are using the Standard MkII rig we suggest that you consider our 8:1 systems which are better suited to that rig.
