The Decoy R-3 Split Ring Medium Class is a premium, highly versatile terminal component precision-forged in Japan for everyday lure angling. Written by Gerrys Fishing, this description highlights how Decoy built the ultimate, dependable connection ring for standard fresh and saltwater configurations.
While light-class rings are too weak for large predators and heavy-class rings are too thick to fit standard lure hangers, the R-3 Medium Class strikes the perfect technical balance. By combining a medium-gauge round wire with high-tensile forging, it delivers immense structural security without adding unnecessary bulk to your lures.

Available Size & Strength Matrix:

| #1 | 20 pieces | 22 lb | 50mm to 70mm light plugs, perch crankbaits, small spinners |
| #2 | 20 pieces | 24 lb | 70mm to 90mm standard minnows, small sea bass sliders, spoons |
| #3 | 20 pieces | 30 lb | 90mm to 110mm sea bass plugs, surface walkers, standard shore jigs |

The Medium-Gauge Versatility Matrix: The R-3 series is engineered as the definitive all-rounder. The round wire gauge is thin enough to pass smoothly through the factory line-ties of medium-sized hard baits, yet rigid enough to comfortably withstand the sudden lunges and head-shakes of powerful predators.
Flawless Spring Back Memory: Forged from high-grade Japanese stainless steel, the R-3 possesses exceptional elastic recovery. When opened with a pair of split-ring pliers to slide onto a lure tow-point or hook eyelet, it snaps back completely flush into its original, tightly closed configuration, leaving zero safety gaps that could trap and fray your line.
Polished Frictionless Inner Radius: The internal curvature of the wire is meticulously polished to eliminate any rough edges. This ensures that hook eyelets, swivels, and lure hangers can slide and rotate completely uninhibited with zero binding, preserving natural lure presentation while reducing the mechanical leverage a fish can use to twist a hook free.
Marine-Grade Corrosion Shield: The R-3 is fully treated with an advanced passive plating process. This forms a highly resilient barrier against harsh saltwater oxidization, preserving both the spring tension and the structural integrity of your connection joints through grueling marine campaigns.
Saltwater Sea Bass Lure Upgrades: The absolute benchmark choice in sizes #2 and #3 for replacing low-grade or rusted factory split rings on standard 90mm to 120mm minnows and surface sliders.
Medium-to-Heavy River & Canal Perch Games: Exceptional in size #1 for strengthening the hook connections on hard-vibration baits and deep crankbaits when targeting specimen perch around heavy structure.
Standard Shore Casting & Jigging: Perfect in sizes #3 and #4 for connecting single inline conversion hooks (such as the Decoy SG-2 Shore Cast) to the rear tail-ties of 15g to 40g metal casting jigs.
The Hook-Up Freedom Rule: When retrofitting hard baits with new split rings, never over-tighten the configuration by using a ring that is too small for the hook eyelet. The hook must be able to swing completely free and dangle loosely under its own weight. If the split ring pinches or binds inside the hook eye, the hook will lock up sideways against the lure body. This not only ruins the swimming action of your plug, but it also creates a rigid pivot point that allows a fighting fish to easily lever the hook out of its mouth. If in doubt, step up one size in the R-3 matrix to guarantee total, fluid articulation.
The R-5 Heavy Class features a thick, flat-forged wire matrix built specifically for high-load big game tactics and heavy-duty pike or tropical lures. The R-3 Medium Class uses a high-tensile round wire profile that offers a much lighter physical footprint and a slimmer wire gauge, making it far more suitable for everyday spinning tactics where lure balance is critical.
With breaking strains spanning from 22 lb up to 50 lb, the R-3 series is exceptionally strong for its size and far exceeds the breaking strains of the braided mainlines and fluorocarbon leaders typically used in standard spinning tactics. Provided the ring has not been permanently over-stretched with incorrect tools during assembly, it will not open up under regular sporting drag settings.
The R-3 Medium Class series is highly versatile and pairs perfectly with standard-wire treble hooks and inline single hooks ranging from size #8 up to #1/0, making it the ideal choice for general tackle box maintenance and custom lure tuning.
