Description
Nytro Free Running Swivel Blocker
Tangles are the absolute enemy of efficient feeder fishing. If your rig is constantly wrapping around itself, you aren’t fishing—you’re just wasting time. The Nytro Free Running Swivel Blocker is a precision-engineered solution designed to create the cleanest, most effective running rig possible.
The “secret sauce” of this blocker is its internal bore, which is specifically shaped to allow you to pull your connection knot inside the bead. When paired with a “twizzled” length of line, it creates a natural boom that kicks your hooklength away from the feeder, ensuring a perfect presentation on every single cast.
Key Features & Benefits
-
Natural Boom Effect: The elongated shape and rigid grip allow you to bury the knot inside the blocker, creating a stiffened “arm” that keeps your hooklength clear of the feeder.
-
Exceptional Line Grip: Made from a high-friction rubber compound that stays put on both monofilament and “slick” braided mainlines.
-
Knot Protection: By housing the knot inside the bead, you protect your most vulnerable point from the constant impact of a sliding feeder or bead.
-
Two Precision Sizes: Available in Medium and Large to suit everything from finesse silverfish setups to heavy-duty distance casting.
-
Eco-Friendly Wire Dispenser: Supplied on wire loops for instant, “no-fumble” application. Just slide it on and you’re ready to fish.

Where to Use Nytro Swivel Blockers
-
Distance Feeder Fishing: Essential when using heavy bullet or window feeders. The blocker absorbs the shock of the cast and keeps the rig streamlined for maximum yardage.
-
River Fishing for Chub & Barbel: Use the Large size to create a robust running rig that won’t tangle in fast-moving water or heavy flows.
-
Commercial Carp Tactics: Perfect for “bomb and pellet” or open-end cage feeder work where you want a 100% free-running, fish-safe setup.
-
Braid-Mainline Rigs: The soft rubber construction is “braid-friendly,” ensuring your expensive mainline isn’t bruised or damaged by metal hardware.
Gerry’s Pro Tip
“At Gerry’s, we see a lot of guys struggling with tangles on the cast. Here is the ‘pro’ move with these blockers: once you’ve tied your swivel to your mainline, twist the last 4-5 inches of your line to create a ‘twizzled boom.’ Now, slide this Nytro Blocker down and firmly pull that knot right into the bottom of the bead. This locks the ‘boom’ in place and makes it point away from the feeder like a stiff arm. It’s the closest thing to a 100% tangle-proof rig you’ll ever find!”
Frequently Asked Questions
Q: Why would I pull the knot inside the blocker?
A: Two reasons. First, it protects the knot from being hit by the sliding feeder. Second, it creates a rigid connection that helps the line act like a “boom,” pushing your hooklength away from the feeder to prevent tangles.
Q: Medium or Large—which one do I need?
A: If you’re using light lines (0.20mm and under) or thin braids for silverfish, go for the Medium. If you’re using heavier gear for Carp or Barbel, or using large-eye swivels, the Large provides a more secure ‘stop’ and a bigger surface area for the feeder to sit against.
Q: Is this rig fish-safe?
A: Absolutely. This is a 100% free-running system. Because it is a blocker on the line rather than a fixed crimp, the feeder can slide off the end of the line in the event of a breakage, meeting the safety requirements of almost all UK fisheries.
Q: Will it work with any brand of feeder bead?
A: Yes. The flat top of the blocker is designed to sit perfectly flush against almost any sliding swivel or feeder bead on the market, including Nytro’s own Connex range.
