No-Twist: Wide plastic slider helps prevent your line from twisting the way narrow sliders do. Easy To Use: Instead of cutting your line every time you want to change up your rig, these sliders allow you to easily switch your sinker styles and weights. Protect Your Rods: Don't let your weights bang against your rod during travel. Instead, easily unclip your weights while you're driving, boating, or rowing! Sinker Sliders Protect Your Line: When your weights rub on your line, they cause damage that weakens your line and can cause your line to break right when a monster fish hits! Stop Losing Fish: Includes 12 sinker bumpers that protect your knot! Weights and sliders hitting your knot can cause damage and weaken your knot. You don't want a weak knot when the fish of your life hits your bait! Weak line and knots can cost you a lot of fish--including the fish of your dreams! This complete set protects your rig in two ways: (1) The Sinker Slider is made from a smooth plastic. Instead of your lead weight sliding up and down your line, wearing it away, the plastic easily slides along protecting your line. Plus, it makes it super easy to change out your sinker. (2) The Sinker Bumpers are made from silicone and protect the knot in your rig. When your weights bang into your knot, your knot becomes damaged and can cost you fish. The bumper sits between your weights and your hook or swivel to protect the knot!
