Reddit mentions: The best shelf clips

You wont be able to buy them as completed shelves. The adjustable shelf supports are a two part system. The part you have which is similar to this and then there are clips that look like this this which fit into the small gaps in the vertical strips that you have. That two part system is the support system for the shelf that you make yourself typically out of plywood to fit the span between the clips. There are things that can be done to make the plywood look better but that's the gist of it.

I'm sure the next question is will the clips that I linked fit in your existing tracks. Unfortunately I can't comment on how interchangable those are. You could look on the manufacturers site to see if they post any dimensions that you could compare yours to. Otherwise on Amazon you could post a question to see if someone will measure one of theirs. The last time I asked for a really specific dimension on there for some cables I got a lot of half assed answers for different dimensions that I didn't ask for. You might have better luck.

Thank you exactly what I needed.

Found a cheaper alternative on amazon as well:

Stoppers is a good name for them, but they're actually called 'tapered sleeves', if you can believe that.

Yes those were the ones I was talking about! Just one problem: the screws are too big for the holes in the closetmaid clips that hold that baby in place. These:

I'll have to see if HD carries something that will fit them. And then there's the matter of whether it will snugly go into my wall. Last time it was a roll of the dice and it was inconsistent from hole to hole.

You should have some plastic sleeves that fit around the poles. do you have any plastic pieces?

Edit here is a picture I am not sure if these are the exact ones for you particular shelves but this is the ide.

Center shelf clips w/bumpers

So the other day, I was putting clothes away in my closet when the entire closet shelf ripped out of the wall and fell on the floor. Literally pulled the drywall anchors out and left holes in the wall. Well as it turns out, the previous owners of this house must have had this happen to them first and they rigged it up with a shoddy repair job. They were using picture frame hooks to hold it up. Needless to say, I now need[ these] (http://www.amazon.com/dp/B000KL4CKI/ref=wl_it_dp_o_pd_S_ttl?_encoding=UTF8&colid=35R0GSXNZ4DZH&coliid=I34MADSWTPNE3).

When in doubt fix it, every restaurant equipment store has those metro rack shelf lock for pennies.
