SR71 BLACKBIRD ZIP LINE TROLLEY

The SR-71 is a proven performer for zip line operations. The 2009 model is built from .101 thick 304 stainless steel. Unlike the competition it is assembled using machined axles which may cost more but give the SR-71 zip trolley unparalleled structural integrity. Safety is always a primary objective, and the SR-71 zip trolley uses an additional back up bolt should there ever be a catastrophic failure during use. The sheaves are case hardened to a 56-58 Rockwell and spin on ball bearings to provide excellent wear characteristics in challenging outdoor environments. Built to accept two carabiners at the attachment point for extra safety.
