Query: Not so hard to adjust

I adjusted this quickly enough by taking the plastic caps off the ends using my fingernails. Not by prying out the inside metal cap. It wasn't so hard. Then I worked the rope out the open end, knotted it to the length I wanted and cut off the excess. I didn't want to bother with tools but if I did I could have adjusted the grommets without knotting the end and then cut off the excess.
