Single Slot Shelf Bracket Stabilizer

Single slot "track" shelving is not very stable on it's own. Generally the larger the shelf the more stable it is. In my case I wanted a place to display my 3d prints but only had about 2 feet of wall width and the shelves ended up being too wobbly. I found the best results with a 7 inch shelf on an 8 inch bracket and this stabilizer. (I just happened to have 7 inch shelves around)
