Stacked tab — one terminal, two connection faces
The 1217043-1: The non-insulated design accepts wire insulation up to 0.200" (5.08mm) diameter and terminates with a standard crimp tool — the stacked geometry gives the wire a receptacle on one side and a tab on the other, so a single crimp serves both a mating half and a daisy-chain takeoff.
Tin-plated brass — current path and corrosion margin
Overall length is 0.780" (19.81mm); the insulation grip range covers 0.150" to 0.200" (3.81mm to 5.08mm), which spans most 10-14 AWG primary wire jackets.
