Lower block assemblies designed to be looped around the mast below the kicker attachment point. This design also allows the end of the primary line to be threaded through and held there rather than at the top of the kicker/vang fitting thereby reducing the load on it, and enabling the downhaul primary line to be optimally positioned. Larger 29/30mm block sizes perform better on the highly loaded downhaul/cunningham. Strops for all block types are available in dark grey and a wide range of colours.
