Sold by the Foot
Sterling OpLux 8.0mm is a favorite with mobile hunters for tethers, lineman ropes, and rappel rope. Sold by the foot. This is in spec and works in conjunction with the Kong Duck mechanical ascender. When used with a Madrock Safeguard or a Figure 8 a backup is recommended. For that the 6mm Auto Block is the perfect option. Use Sterling 6mm TRC for Prusiks with OpLux
When using OpLux to create your own Tether or Linemans Belt make sure to order an extra 2 or 3 ft to accommodate your figure 8 on a bite and stopper knots
