About the GTA-358 & HLB-472 Ground to Air Blocks
Constructed of lightweight, high strength aluminum alloy for maximum strength at minimum weight. Because sheaves are mounted on ball bearings for minimum friction and are recessed within the frame, these blocks are ideal for use with synthetic ropes. HLB-472 model available in standard or “open side.” When ordering specify fitting.
