Shoot a brad thru the hole in the support and into the shelf.
It will remain proud of the shelf underside enough to hold the
shelf but you wont see it.

I have a cabinet with adjustable shelving which is open on opposing
sides and I'm looking for ways to secure the shelves from sliding out.
I'm using standard shelf pins like this
http://www.rockler.com/product.cfm?p...8&cookietest=1
but I realized someone should make a version with another pin sticking
up (instead a hole or a friction pad) which I can drill holes in the
bottoms of the shelves to accept. Rockler and Lee Valley don't have
anything like it, though, so it probably doesn't exist :-)
I suppose I could put pins in the bottom of the shelves that would fit
into the holes in the supports I have now, but that's not as pretty a
solution. I want to maintain ease of shelf rearrangement.
Is that the best I can do?
