Double Loop-to-Loop Connection

By Jon B. Cave


Because the standard loop-to-loop connection is versatile, simple to use, and slides through rod guides easier than other knots, most of us rely on it at some point to fasten a loop on one part of the line system to a loop on another.

That connection can be between backing and fly line; fly line and leader; or within the leader configuration itself. The union formed by joining one loop to another is a strong one when properly done (see photo 1); however, if the loop-to-loop knot isn’t executed correctly by drawing the loops tightly together so that they remain seated in place, a hitch may develop at one of the loop ends and weaken the connection (see photo 2).
