In this second part of my preview of On the Line, I move on from eccentric rope clamps, coving the less well known rocker arm device. Rocker Arm Invented by Russian climber Victor Kozlov in 1975, this design and mechanism radically departed from Western designed eccentric rope clamps established by Petzl and Jumar, yet offered several advantages over conventional rope clamps.

Hi Andy,
Not expecting a reply but was just curious on your opinions of the suitability of a rocker for lead rope solo. After reading Rob Thornton's blog post http://soloalliance.blogspot.com/2011/12/self-belay-with-troll-rocker.html I was tempted due to the cheaper cost and seeming simplicity.
I would be using the system with a backup but wanted to know if this was something you would trust.
Thanks
Hi Andy,
As usual, interesting article on something I knew nothing about. Saw the following which looks like similar mechanism. But, £24??!!?? Too good to be true? https://www.ebay.co.uk/itm/373602239854?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=FiFjXau-RZm&sssrc=2349624&ssuid=mb5c6Hx9S3W&var=642610115224&widget_ver=artemis&media=COPY
