Description
The Cox & Rawle Copper Double Leader Sleeves, often simply referred to as “double crimps,” are essential terminal tackle components used for creating secure and strong loops in fishing lines or wire leaders.
Here is a breakdown of their features and common specifications:
Key Features
- Material: Manufactured from soft copper (or copper alloy). This material is chosen because it is relatively forgiving and minimizes the risk of damaging the line or wire during the crimping process, while still providing a strong hold.
- Design: They are double-barrel sleeves (two parallel holes) designed to create a loop by threading the line/wire through one hole, around a swivel or hook eye, and back through the second hole.
- Finish: They are burr-free and non-abrasive to prevent damage to the line/wire. They also feature a corrosion-resistant finish, which is crucial for saltwater fishing applications.
- Usage: They are ideal for both multi-strand wire (like the Cox & Rawle Pro Rig Trace Wire) and monofilament (mono) leaders, especially in heavier breaking strains where knots can be bulky or unreliable.
Common Sizes and Packaging
The sleeves are sized by their Internal Diameter (ID), which determines the line or wire size they are designed to accommodate.
