Profurl's 2:1 Halyard Blocks are designed for the NEX Furler range, with options available to suit NEX furlers sizes 2.5 or larger. The block is directly integrated into the swivel, avoiding any twisting in the connection, and they can be used as the upper or lower end fitting. The low friction ball bearing sheave provides impressive efficiency even under high loads.
Incorporating a 2:1 halyard block in your furling system will greatly increase your ability to achieve adequate halyard tension, resulting in a tight, secure furl every time.
