elfa Independent Shelf Pins
These are great!
I have a set of 24 inch shelves on wall mounted rails in my office. These pins keep my 8" and 12" shelves tight on the brackets. It takes a bit of effort just to pop the shelf up of the bracket and I'm confident they will not be moved inadvertently. I've not used the wire connectors, but playing with them in the store, they do not seem as secure as these pins.

If you have "elderly eyes," you will need glasses to be sure you're putting them in facing the same direction as the marker arrow is quite subtle. Other than that there are no drawbacks to these pins. They lock in place. They are completely hidden when installed. They work the way they should.

These pins are nicer than the wire version
I like these pins far better than the wire version.

Does its job. Just watch for the arrows to tell you which side faces in/out.
