Pouring your own lead weights or customizing your tackle box configuration offers an unmatched sense of bankside satisfaction, while significantly lowering the cost of your terminal gear. The Gemini System 100+ Side Grip Assembly Kit provides everything you need to build or overhaul your own high-performance breakout sinkers. Designed to be used in conjunction with the legendary Gemini System 100+ Breakout Sinker Mould, this complete do-it-yourself component pack contains premium, marine-grade parts to construct 10 fully functioning anchor leads.
The standout feature of this specific configuration is the implementation of Gemini’s highly specialized Side Breakout Grips paired with Long Tail Wires. Unlike standard nose-cone wires that angle straight down, side grips are precision-engineered to sit lower and wider out from the lead profile, providing a devastatingly effective bite into loose sand, shifting shingle, and soft mud. The Long Tail Wires are the ultimate choice for streamlining your setup, giving you an extended central shaft that serves as a highly stable, integrated flight tracking tail, while acting as a perfect anchor point for building clean bait-clip or pulley rig systems directly off the base of the weight.
Product Type: Complete DIY breakout sinker component kit.
Grip Style: Side Breakout Wires (engineered for maximum low-profile lateral hold).
Tail Configuration: Long Tail Wires (ideal for stability, aerodynamics, and bait-clipping).
Head Style: Threaded, high-impact polymer breakout heads in sleek Black.
Mould Compatibility: 100% optimized for the Gemini System 100+ Breakout Sinker Mould.
Kit Capacity: Includes enough premium components (excluding raw lead) to make 10 complete sinkers.
Kit Contents:
10 x Long Tail Wires
40 x Stainless Steel Side Breakout Wires
10 x Black Threaded Breakout Nose Cone Heads
DIY Lead Pouring Winter Projects: The perfect component kit to keep you busy during cold winter evenings. Pair these components with your Gemini mould to pour a custom batch of fresh weights, ensuring your tackle box is fully stocked for the upcoming season.
Heavy Lateral Tides & Shifting Sands: The ultimate layout for holding bottom in fast-moving estuaries, deep beach gullies, or heavy coastal swell. The wide stance of the side grips forces the weight to anchor instantly where standard straight wires might pull through the sand.
Clipped-Down & Pulley Rig Building: Perfect for anglers who build advanced shore rigs. The extended length of the long tail wires provides ample room to slide on Gemini bait clips, Genie links, or neat impact shields directly over the tail, keeping your hook baits completely streamlined during high-power casts.
Pro Tip: When assembling these side grips into the black polymer heads, make sure the wires are seated flat and flush before locking them down. If you are fishing in exceptionally turbulent, weedy conditions and find the side wires are tripping a bit too early from loose weed hitting the line, try shifting to a thicker grade of Gemini PVC roller sleeving over the pins. This slight increase in friction hardens the breakout threshold, allowing your sinker to stand firm against heavy debris while still opening cleanly when a fish hits or when you give the rod a firm strike to reel in!
Q: Does this kit include the raw lead or the metal casting mould?
A: No. This is a component assembly kit containing the internal wires, external side grip pins, and threaded plastic nose cones. You will need a Gemini System 100+ Mould and a supply of raw lead to melt and cast the actual weight bodies yourself.
Q: What size or weight of leads is this long tail kit best suited for?
A: While these components are fully modular and can technically be used across various sizes in the Gemini mould system, the combination of long tail wires and side grips is traditionally favored for making mid-to-heavy beachcasting leads from 150g (5oz) right up to 210g (8oz), as the long tail beautifully counterbalances heavier lead profiles in mid-air.
Q: Are these wires prone to rusting after a few trips out to sea?
A: Not at all. Gemini utilizes premium, high-tensile marine-grade stainless spring wire for both the tail shafts and the breakout side grips. They are completely rustless, highly resilient, and designed to withstand hundreds of breakout cycles in harsh saltwater environments without losing their structural shape or spring memory.
