ACOUSTICAL DIRECT FIXATION FASTENERS

ADFF

LOWER NOISE AND VIBRATION

Progress Rail’s ADFF was created to provide noise and vibration attenuation expected from high resilient DF units while matching the anchor bolt patterns and rail seat elevation of standard DF units. Until now, that has never been done. The acoustical performance has been verified by independent, recognized acoustical track experts and we have been awarded multiple contracts to date. High Attenuation DF products have been a specialty of Progress Rail for over 35 years and this product is a significant step forward in DF innovation and evolution.
