Here is the Jurassic insulator with Jurassic hook

The hook gets screwed into the insulator

A 6mm hole is required on the bracket

With the hook just screwed onto the bobbin, you will hook it into the bracket

Once the hook is in the bracket, you will start turning the insulator. The hook will grab onto the inside of the bracket and start tighten the insulator to the bracket
