We describe a support for the University of Rochester gravitational wave detector. The support is a two-stage filter with springs made of aluminum and a brass intermediate mass. With this support we have measured a mechanical quality factor for the fundamental mode of a 200-kg aluminum cylinder of 2.2 x 10/sup 7/ at 2302 Hz at 4.2 K. The filter attenuates vibrations by -130 dB at this frequency.
