Thank you for your answers and sorry I am late to respond, for some reason I was never notified that anyone had responded to my question.

I didn't think there would be room with that mechanism located there but wanted to check.
Can anyone recommend a good won't kill the bank brand that hopefully has a set that will handle up to 1/2"?
