North States 2-Way Squirrel Baffle

If hanging a birdfeeder, how do you set up the hanging baffle on top of the feeder? Not sure how to securely set this up via hanging

Can squirrels chew this? Also, if they can jump to it, will it break?

If looks like this baffle pivots, which would allow squirrels to drop onto larger bird feeders underneath. Can the baffle be fixed somehow?

I have a large, long bird feeder I need to protect - will the squirrels be able to slide down the baffle to the bottom of the feeder?
