Abstract
Abstract A safety working lanyard interconnects with a D-ring on a safety belt to provide a safety line that is versatile and readily adjustable in length while in use. End hooks connectable to the D-ring are secured to each end of a length of safety line, and a working hook has an eye that is freely slideable along the length of the line and is also trapped between the end hooks. The end hooks are sized to pass through the D-ring on the belt and connect to the working hook, which is too large to pass through the D-ring and large enough to hook onto a ladder rung.
