Double Tube Ferrule Terminal Kit with 4-Sided Crimping Pliers

Our review of the Double Tube Ferrule Terminal Kit finds it best suited to electricians, maintenance techs and hobbyists who crimp a wide range of stranded conductors and need a complete kit. The single biggest reason to buy is the combination of a ratcheting, 4-sided square jaw crimper and a generous 1200-piece set of single and double ferrules that covers 0.08-16mm2 (28-5 AWG), so you can reliably terminate everything from fine signal leads to heavier control wiring without hunting for additional ferrules or a separate tool.

Key Features

• 4-sided square jaw: The 16-4A square claw creates firmer, more uniform crimps on tubular terminals for better mechanical and electrical contact.
• Wide crimp range: Works across 0.08-16mm2 (28-5 AWG), letting one tool handle very small signal conductors up to thicker control wires.
• Ratcheting mechanism: The ratchet-type connecting rod reduces hand fatigue and ensures a complete crimp cycle for consistent results.
• Large ferrule assortment: The 1200pcs single and double ferrule set includes sizes for AWG 6 through 22, so most wiring jobs are covered out of the box.
• Durable materials: Copper conductors with silver-plated surfaces improve conductivity and resistance to oxidation for longer-lasting terminations.
• Comfort grips: Non-slip lagging handles provide a comfortable grip and better control during repetitive crimping tasks.

Who It's For

This kit is aimed at professional electricians, panel builders and serious DIYers who regularly terminate stranded wire and need a reliable tool plus a broad selection of ferrules. The combination of a precision ratcheting crimper and 1200 ferrules makes it especially useful for maintenance shops and equipment installers who value consistency and the convenience of a full set.

Those who rarely crimp or only work with very large lugs might find the range and volume excessive; similarly, if you require insulated disconnects or specialized automotive terminals, look for a kit tailored to that terminal type rather than this ferrule-focused set.

Pros & Cons

Pros

• Comes with a comprehensive 1200pcs ferrule assortment so most connector sizes are available immediately.
• Ratcheting, 4-sided jaws produce secure, uniform crimps that tame stranded wire and improve connection reliability.
• Silver-plated copper ferrules offer good conductivity and resistance to oxidation for long-term performance.
• Comfortable, non-slip handles make repeated crimps less tiring.

Cons

• The kit includes many small ferrules that may be unnecessary for users who only work with a few common sizes.
• Some customers comment on mixed perceptions of copper content and quality, so heavy industrial users may want to inspect materials for their application.

Our Verdict

The kit offers strong value for anyone who needs to terminate a broad span of stranded conductors reliably: the ratcheting, square-jaw crimper and large ferrule assortment reduce trips to the parts bin and speed panel and field work. It is a practical, cost-effective package for electricians and technicians, though users with very specialized terminal needs should confirm material details for their environment.

Frequently Asked Questions

Does the crimper cover very small and larger wires?
The tool covers 0.08-16mm2 (28-5 AWG), so it handles both fine signal wires and heavier control conductors within that span.

Are the ferrules plated and why does that matter?
Ferrule conductors are copper with a silver-plated surface, which improves conductivity and helps resist oxidation over time.

Is the tool comfortable for repeated use?
Yes; the ratcheting mechanism and non-slip handles reduce hand strain and make repeated crimps easier and more consistent.
