Screw-Tight Rod Post Insulator White
The easy spin-on nut screws onto the back of the insulator to secure tightly to the fence post. Designed for low impedance and standard duty fence controllers, it fits 1⁄4" to 9⁄16" diameter posts. Two large shields prevent arcing and a uv-protected material resists weathering. 45 degree front end loading accommodates all wire sizes.
