Bare stranded wire under a terminal screw is a slow-motion failure waiting to happen — strands fray, connections loosen, and resistance climbs. Ferrules solve that by giving stranded wire a solid crimped end, but only if you have the right crimper and a reasonable range of ferrule sizes on hand. The SOMELINE kit bundles both into one box, which is why it’s become one of the best-selling ferrule kits on Amazon.
What It Is
This is an all-in-one ferrule crimping kit: a ratcheting crimp tool sized for AWG 24-8 ferrules, plus 23 different ferrule sizes and roughly 1,800+ ferrules total, packed in a two-layer storage case. It’s aimed at panel builders and electricians who need to terminate stranded wire cleanly without buying a crimper and ferrules as separate purchases.
Key Features
- Ratcheting crimp mechanism with a professional-grade crimping die, sized for AWG 24-8 ferrules
- 23 ferrule sizes included, made from tinned copper with a nylon insulating sleeve
- Ratchet action ensures a full, consistent crimp every time — it won’t release mid-crimp
- Two-layer portable storage case keeps ferrules sorted and the crimper protected
- Suitable for panel wiring, automotive, machinery, and general electrical maintenance work
Pros and Cons
With over 8,600 ratings at 4.7 stars, this is a well-proven kit, and the ratcheting mechanism is the detail that matters most — a non-ratcheting crimper lets you under-crimp without realizing it, which defeats the purpose of using ferrules at all. Having 23 sizes on hand also means you’re rarely stuck without the right ferrule mid-job.
Like most bundled kits, the ferrule selection is generalist rather than deep in any one size — if you burn through a specific size constantly (say, on a production panel line), you’ll want to buy refills for that size separately rather than relying on the kit’s stock alone.
Who It’s For
Panel builders, electricians, and maintenance techs who terminate stranded wire regularly and want one kit that covers ferrule crimping without assembling the tool and ferrules from separate sources.
Verdict
For under $30, this is a genuinely useful all-in-one ferrule kit with a proper ratcheting crimper — a sensible pickup for any panel-building toolbox.
