BKK Double Barrel Crimps are designed to form clean, secure loops with flared ends, allowing the line to slide naturally without creating sharp edges that could damage the leader. Made of durable copper with a black nickel finish, they combine strength with discretion underwater. Compatible with fluorocarbon, jacketed nylon, or stiff monofilament lines, these versatile crimps adapt to a wide range of rig configurations. Available in several sizes to accommodate different line diameters, BKK Double Barrel Crimps guarantee a professional result every time.
