Plasti-Grip ring terminal for 4 AWG
The 55680-2 is the 1/4-stud member of TE's Plasti-Grip ring terminal line, accepting 4 AWG wire with a tin-plated copper contact and yellow PVC insulation. Rated for free-hanging crimp termination, the flat-sided barrel and 0.048" (1.22mm) thickness suit heavy-duty power connections where the stud size matches the panel clearance.
Stud size and series siblings
Within the Plasti-Grip 4 AWG family, the 55680-2's 1/4 stud sits between the 10-stud 52043-2 and the 3/8-stud 1-52266-0 — the 0.048" (1.22mm) thickness, tin plating, and PVC insulation are shared across the three, so the choice reduces to the stud hole diameter matching the mounting point.
