0.71-INCH THICKENED STEEL：This ferrule crimping tool uses a 0.71-inch stainless steel body for a more substantial holding surface during hammer-operated crimping.
23-4/0 AWG CRIMPING RANGE： The adjustable jaw handles compatible wire ferrules from 23 to 4/0 AWG, covering small and large-gauge ferrule crimping with one manual tool.
ADJUSTABLE SQUARE CRIMP：Set the jaw opening to match the ferrule size. When correctly positioned and struck, this wire ferrule crimper forms a square-style compression.
SIMPLE HAMMER OPERATION：Place the hammer crimper on a solid surface, insert the ferrule, adjust the jaw, and apply controlled strikes. No battery, hydraulic pump, or power supply is needed.
FOR HOME DIY & SMALL PROJECTS：Designed for home DIY, small electrical repairs, and occasional large-wire ferrule work. Best for low-volume use, not repetitive industrial or factory production.
