Open barrel contacts demand a proper double crimp: a B-type crimp on the conductor and a separate B-type crimp on the insulation support — pliers mangle them, generic crimpers approximate them.
The Sargent 1028-CT does them correctly, with five precision cavities dedicated across the medium wire range: two insulation crimp cavities (A: 18-14 AWG, B: 24-20 AWG) and three conductor crimp cavities (C: 16-14 AWG, D: 20-18 AWG, E: 24-22 AWG).
Close the tool twice per termination — once on the conductor wings, once on the insulation wings — and the result is the textbook B-crimp profile connector manufacturers actually specify.
The conductor crimp grips the strands for low resistance; the insulation crimp supports the jacket against vibration. Coverage spans 24-14 AWG (1.5 mm² and 2.5 mm²) — the range of automotive-style connector housings, control harnesses, and equipment interconnects.
Made in the USA by Sargent (Rostra Tools) and compliant with the US Berry Amendment — a genuine domestic-materials tool.
At 8 inches long, it's a solid bench and field crimper that Rostra's own channel lists at considerably more than our price. If you've been folding open barrels with needle-nose and hoping, this is the fix.
