Review on Optimized Morris 21899 Service Entrance Insulator by Marc Gallner

was damaged, installed and connected to the electric fence wire, you have to run the wire up and through several handles so I had to put an insulator in the roof around the wire To secure the bolt is about 8" long so it was easy to drill a hole (apply gasket to the base), insert into the hole, go underneath and tighten the nut (uses a thumb washer under the nut) to fit snugly my needs
