Other reviewers have pointed this out, but I've decided to give my 2 cents. The notches on them are tiny and couldn't hold any of my hooks without loosening at the slightest movement. I've included a picture of the locks I have at Home Depot for comparison purposes. I only needed a few and since they are non-returnable I modified them. They can be saved by heating them a bit and bending them to give the locks a tighter grip. I used the heat gun at high speed and gave each side a few seconds, flexing them to give them shape and blowing on them a bit to keep the plastic cool and prevent bouncing. They don't hold that tight (hooks wobble a bit) but snap into place. If you need more than a handful I would look elsewhere as not worth the time/effort.
