Screw-In Ring Insulator White Pack of 25

The Screw-In Ring Insulators have been re-designed to incorporate a steel reinforced ring to give additional strength. Made with a heavy screw as its base and a continuous steel reinforced ring, this insulator has the strength to hold in old locust posts or in the soft wood of old telephone poles. The wire, held 2" away from the post, is easy to install and remove but is unlikely to come off at other times. 25/pack
