The Field Proven Calls Universal Lanyard Drop was developed so you can securely add additonal calls to any lanyard. Made with 5.5 foot of U.S. Military grade parachute cord, capable of holding 550 lbs and a stainless steel quick link with a safe working load of 300lbs… this is the world’s strongest lanyard drop. The Universal Lanyard Drop also has a “Knot Locker” system that slides down ensuring the quad halter cinch knots will never loosen until you choose to change out calls. Yes it is way over engineered…and yes we would not want it any other way.
