Triangles and bars should not turn in the plane parallel to the mirror.  
Kriege and Berry suggest cutting a circle of thin plastic and attaching 
this to the triangles (or bars) with double sided adhesive tape.  The 
plastic should be thin enough not to transmit significant forces in the 
axial direction, but stiff enough in the plane of the mirror to prevent 
rotation.  The center of the circle can be cut out to allow better 
ventilation to the mirror.
