Grommet placement in pole banners

[RMarshall]

We just got our first order for pole banners and we're outsourcing to a local trade printer.

We ordered several samples before ordering the full quantity and the samples don't have any grommets.

I can add the grommets in house but I'm not sure where to put them...
I've been searching around online and on here but haven't seen any specifics.
I'm a little confused because some of what I see makes it seem (no pun intended lol) like the grommets help reinforce the hem, while other things make it seem like the grommet is just for attaching the banner to the hardware.

Do you put the grommets directly through the sewn seams or just below the seam/pocket?

Just past the stitching. This is how they come from our vendor (who also supplies the hardware)

When don't typically stitch pole pockets when done in-house. We use banner hem tape and grommet thru that.

If the banners are made correctly they'll be double sewn through the loop and down the edges. Then, below the stitching is fine, as the stitching will help it from tearing out. If the edges are not sewn, I'd suggest putting in on the sewn loop stitching. Otherwise, if there's nothing to help hold it together, strong winds can easily pull them out.
