I have used these with quarter circle glass shelves in the corner. The mounts themselves are good, the set screw has soft padding to cushion and grip the glass and once installed they look nice. The dowels included in the kit were useless. The screw could not be tightened enough to press it against the wall and prevent the bracket from twisting. Shelves installed with these anchors were unstable. I recommend the mount, but save yourself the hassle and get some good wall anchors like the EZ Ancor Twist-N-Lock. The combination did an excellent job on installation.
