Harken 2:1 Sheave Adapter for Unit #1

Harken®'s Code Zero accessories are provided to offer additional options for ease of use and maintaining proper functioning of all hardware involved in a Code Zero furling system. Since furling a Code Zero sail requires very high luff tension, this 2:1 Sheave Adapter is available for the higher load units such as CZ Unit #1.

This adapter can be use on either the upper or the lower unit, but installation on the upper is advised to prevent the halyard from twisting.
