Wild Country MK2 Ropeman Ascender
Ropemen are an odd device that initially might not seem that useful or flexible; not as light and simple as a Tibloc and not as easy to handle and efficient as an Ascension. Then you start using one ...
As a simple ascender that securely and reliably bites they are actually really very good, but it's their non-conventional (and non-recommended) uses where they come into their own. Coupled with Reverso style Guide plates they can be incorporated into the system to provide a hoist to a stuck second and whilst simul-climbing (highly non-recommended of course) they can be used to protect the lead climber from a less than elegant tug from the wall in the event the second were to slip.
The MK2 is recommended for Single and Half ropes down to 8mm..
