Wolverine Tackle’s Super Rings superior (3) coil design and special heat treating process combine to make these split rings unmatched for strength and quality! Certified testing by an independent laboratory has confirmed the strength of the split rings as listed. These split rings are by far the strongest and most secure split rings we have come across due to the 3 coil design used exclusively by Wolverine Tackle. The added strength of the split rings does however increase the diameter significantly. We offer the Wolverine Tackle Zinc Super Split Rings in three sizes: 3, 4 and 5. 15 per pack.
