BKK Double Barrel Crimp Sleeve

Product highlights

The crimp sleeve BKK Double Barrel Crimp is designed to build strong, neat and durable leaders, especially when your rig must not compromise on reliability. Thanks to its double crimp design (two chambers), it keeps the leader material stable during crimping and helps create a regular, clean and secure loop.

The flared ends are designed to promote smooth passage of the leader material, helping reduce sharp angles and pinch points. The result is a safer rig, better leader longevity, and a cleaner presentation when fishing with lures, live bait, or predator-specific setups.

Technical features

• Type: double crimp sleeve (double chamber) for leaders
• Material: durable copper, designed for reliable crimping
• Design: flared ends for cleaner loops and better respect of the material
• Uses: loop making and connections on leaders
• Compatibility: fluorocarbon, monofilament and wire
• Variations: available in different sizes to fit multiple diameters

Benefits and key advantages

Clean, consistent crimping: the double chamber stabilizes the material while shaping it, making it easier to achieve a symmetrical loop and a professional finish, even on stiffer leaders.

Hold and reliability: a good crimp is essential to reduce hook pulls and break-offs. This sleeve is designed to deliver consistent strength, suited to the demands of predator fishing and situations where strikes can be violent.

Leader-friendly design: the flared ends help reduce the risk of marked edges at the loop, preserving fluorocarbon, monofilament or wire as much as possible and improving the durability of your rig.

Versatility: whether you are building wire traces for toothy fish or fluorocarbon/mono leaders for other techniques, this leader crimp sleeve fits easily into your rig-building setup. It works for making loops for snaps, swivels, rings and other common connections, depending on your rig.

How to use

For reliable results, choose a sleeve size that matches the diameter of your material. Thread the leader through the sleeve, form the loop around your accessory (or a tying jig), then pass the tag end back through the sleeve. Adjust the loop without overtightening it so it keeps proper articulation.

Then crimp it using a suitable crimping tool, applying steady and controlled pressure. Avoid over-crushing the sleeve: crimping too aggressively may weaken some materials. The goal is to achieve a firm, even hold and a clean loop. After crimping, visually check the symmetry and perform a careful pull test to confirm the strength of the rig before fishing.

FAQ

Question 1: What is a double crimp sleeve used for in fishing?

Answer: It is used to create a strong loop on a leader (fluorocarbon, monofilament or wire) by replacing a knot with a reliable crimp, ideal for connecting a snap, swivel or ring.

Question 2: Is this sleeve compatible with several leader materials?

Answer: Yes, it is designed for use with fluorocarbon, monofilament and wire leaders. Just select the right size for the diameter you are using.
