conduit nuts are not plastic they are metal very strong, not burning you here but I dont think people are just throwing anything in there for lift, everything I have read throughout this has been things that are proven to work very well. The conduit nuts are very strong like I said and can hold up very well, maybe go by a hardware store and see for your self.

Maybe part of it is we talk and use names of things that you are not familer with and we need to do a better job of explaining what we mean that way you or anyone else will not think we are running around in unsafe Libertys!
