Fixed Multibar Descenders

Many of these are whaletails. These achieved popularity inpopular in Australia, but because of some early incidents, they never caught on in the USA. Personally, I think that their weight makes them too heavy for general use, but their ruggedness is advantageous for some rescue applications.

Ive also included some related and rather unusual devices here.
