Not a newbie
the issue isn't the grommets or the banner, though they will eventually fail over time. the main issue is the force on the posts. they will get ripped or bent like twigs with a large banner. remember a chain link fence is just a big mesh banner with large holes.
I understand this and the customer know it's just a temporary signage. But since for now there is no problem with the banner, I just want to make sure the banner will stay on the fence. The place I buy the stainless tie wrap have a model rated for 485lbs, I have to check if it will go though my grommet.
