Cox & Rawle Copper Single Leeder Sleeves

The Cox & Rawle Copper Single Leader Sleeves are a type of crimp used in fishing rig construction, primarily for creating very small, neat, and strong connections, especially in lighter to medium line classes.

They serve a different purpose than the double sleeves, as they only have one hole and are used in a different manner for securing loops or components.

Key Features and Purpose

• Design: These are single-barrel sleeves (one hole) which function as a stop or fixing point on a line.
• Material: They are constructed from copper (or a copper alloy), providing a balance of malleability for secure crimping and corrosion resistance for saltwater use. They are specifically noted as being copper, not the inferior brass sometimes used by other brands.
• Finish: Like the double sleeves, they are burr-free, non-abrasive, and have a corrosion-resistant finish (often Black Nickel) to protect the line and withstand the marine environment.
• Usage:
  • Stops: They are commonly used to create fixed stops or anchors for components like beads, swivels, or rig bodies on the main line of a rig (e.g., in pulley rigs or running ledger rigs).
  • Wire/Mono Fixing: They are suitable for securing single-strand and multi-strand wires as well as monofilament lines. For creating a loop, a knot is usually still required, or the line is simply doubled over the component and passed through a single sleeve before being crimped.

Common Sizes and Packaging

The single sleeves are available in a very wide range of sizes, designated by a size number and their Internal Diameter (ID) in millimeters. The size range is much finer than the double sleeves, catering to thinner lines.
