NFPA 1983 strength requirement for Descent Control System Components is 22 kN (4,946 lbf)
The classic CMC Rescue 8 has been refined for even better performance with the current selection of rescue rope sizes from 7/16 to 5/8 inch.
Today 5/8 in. rope is no longer common and the smaller dimensions of the new design provide greater control.
CMC’s exotic proprietary black finish on the aluminum model provides outstanding wear resistance.
The nickel-chrome plated steel model excels in the exceptionally high wear situations such as helicopter operations or sandy, gritty environments.
The extended carabiner hole provides room for multiple carabiners.
Both models are machined from 1/2 in. plate.
Large hole dia.: 2.5 in.
