Product review (1 stars): Possible Fixes
Second one just broke.  Saved old one and used super glue on it.  Plus added metal tape to re-enforce, will see how long this one last. Have three future fixes. 1) make thin metal sleeve, u shaped about two inchec long to cover the end of rail. Must go over the edges on each side. 2)  Take out frame, rail is attached to.  Where rail makes contact with frame, drill two holes, insert two 6/32 machine screws with nuts. Now just hope the frame holds up. 3) Last option, buy a dozens rails.
