It doesn’t catch anything.
However I don’t think it’s as strong as the OEM one in the MK7. The bonnet seems to open quicker than it should and shudders a bit at the top. So you’d nearly want to keep a light hold of it as it opens. Similarly when closing it does drop quicker than I’d like, once it passes the half way down mark.
Still - way better than the manual strut which I also removed.
