Probably easier to just leave that design feature in place when the media lost it's wire backing, but don't be surprised if some day the Ultra goes to fiber end caps. Only "grip" I have about Fram's fiber end caps is they could make them a bit thicker, but what they have seems to work for the intended use.
Yeah I don't really despise or hate them like some people but if Fram gave me the option of a fully covered end cap in fiber or metal.. I would just take the metal.. but otherwise if it is a fairly stout media, then I prefer a small glue disc in the center that is covering much less area like the old A01's, some current Full brand and a few others.
