The Gooseneck Ring Insulator is made with a heavy screw as its base. This gives it the strength to hold itself in cracks of old locust posts or in the soft wood of old telephone poles - and most anywhere in between. The rod has a 90 degree bend down then has a 180 degree bend up. The weight of the wire is resting on top of the end of the bent rod to give better strength and electrical insulation.
