I used these to add plywood to half a shelf in a closet to make it a full shelf so I can install drawers/drawers. Worked great. These brackets are strong and the screws are the perfect length to secure the brackets to the shelf/side of the cabinet without breaking through. One review says something about them being "ugly half painted" and that almost put me off buying them, glad I took the chance. The white part is NOT paint but a kind of plastic cover to protect the paintwork that can be easily removed. Not sure why the other reviewer couldn't figure it out. So don't be put off by this erroneous recall - if you need braces, buy one and remove the cover prior to installation.
