Details For maximum lure action and fish-catching success when casting or trolling crankbaits, use Lindy Crankbait Snaps. A lure must be free to dart, dive, wiggle, and wobble without the constraints of direct ties to the lure—and without the action-killing burden of bulky swivel-snaps and leaders. These lightweight dark-colored snaps open and close easily, facilitating quick lure change and less down time!
