As others have noted, the price for two corners and bolts seems high. However, I don't have the time or inclination to bend/drill/cut/powder coat these things, so the OEM price was just great. Others have mentioned zip ties to keep them from rotating/tipping. My solution was a small self-tapping screw. You don't need much to secure it, but you can tighten just one nut. I have a 108 watt light which is quite powerful so it catches the wind. A screw just won't break it. Fortunately, this is easy to fix. Since I use them for task lighting, I actually keep a "stock" so I can flip it down to light up the bed.
