The same uses apply to the toggled lark’s head as to its untoggled counterpart, the lark’s head. Procure a ring large enough to fit over the doubled line used for the knot.
A. With the ring and toggle ready, form a bight with its legs together. Pull the bight through the ring and down over the legs. Push the legs forward through the bight and hold them there.
B. Position the toggle behind the legs where you pulled them through the bight but in front of the bight.
C. Pull down on the legs to tighten the bight and legs against the toggle. Even pressure must be applied to the load on the legs to maintain the knot’s integrity.
