The Kong Big 8 is a Figure 8 descender for abseiling and rappelling that is available manufactured in either Aluminium or Stainless Steel.

 

As the name suggests this is a large Figure 8 device that is best on thicker ropes, although skinnier ropes can be connected through the small middle slot for increased friction. The stainless-steel version is available in black as a bespoke item (MOQs apply) and provides a virtually indestructible abseil/rappel device.

 

The design features include wings/ears to stop the rope from being pushed back over the top of the Figure 8 when going over edges and accidently locking itself off with an impromptu larks-foot knot. A large central hole that increases the probability of the device to be able to pass knots in the system. 

 

This descender is tested to meet the requirements of EN15151-2 for ropes 9 to 16 mm thick, although it is very fast on skinny ropes unless the middle slot is used.
