The need for a block that can withstand increased loads on the ILCA vang has led top sailors to seek a double-sheaved XHL block, which has been over-engineered to handle working loads up to 600Kg without sacrificing dynamic performance. With twin rows of stainless-steel ball bearings and a precision plain bearing washer, the XHL block is designed to handle extreme static loads without compromising on low load dynamic performance. Its aluminium body features "ears" for easy attachment and a stainless-steel sheave suitable for use with both rope and wire.
