Abiko KR 4-4 G — compression (crimp) copper tube cable lug for terminating a 4 mm² conductor onto an M4 stud. The barrel is formed from 99.95% electrolytic copper, tin-plated (Cu/Sn), with a fork/spade tongue and a cable inspection hole for correct conductor insertion. The tongue is an open fork (spade) that slides under a partly-loosened nut without full removal. Accepts stranded (IEC 60228 Class 2) and flexible (Class 5) copper conductors; crimped with matching Abiko/Elpress dies to a gas-tight, low-resistance connection whose crimp performance is verified to IEC 61238-1. Applied in low-voltage power distribution, switchboards, motor terminations and marine and offshore installations.
