Plasti-Grip vs Solistrand ring terminals
The 2-34150-1 is insulated (PVC) with a 1.090" (27.69mm) overall length; the non-insulated Solistrand 1377172-9 also fits a #1/4 stud at the same 0.031" thickness but is shorter at 0.855" (21.72mm) and accepts 14-16 AWG. For a gold-plated option at 18-22 AWG, the Solistrand/Strato-Therm 133521-1 uses an 8 stud and a 0.281" (7.14mm) outer width.
