I just got mine, and they added a little warning tag stating that ... If the surface you install them on must be perfectly level or the feet will snap...I think they are made out of cast metal and therefore very brittle. Is it possible it wasn't quite flush?? If they wont warrantee it run a long radiator hose clamp around the top of it and down the sides and screw it down with sheetrock screws to your platform, then sock the clamp down... It aint goin' nowhere my friend... Hope that helps...Al...
