I have used the big ropeman on my new resctech 8mm and it holds great, with at least 3 teeth outside the unit…..not even touching the rope under load. Just low level testing only so far, btw.. I just don’t like the sharp teeth that bite into the ropes. I wish they’d make a smaller ropeman 1 using the same blade type teeth instead of those sharp points.
Since it is so far out of spec, I ordered a hulk carabiner to hopefully fill some of that space. Til then I am using my elite 9mm for a separate tether. I have a heavy round steel biner that is twice as big around as most of my others, it weighs a lot and is a no name brand, so I dont use it but it filled that void. Now when I did use it, I’d have to open the ropeman all the way just to get it in there……diameter of carabiners have to be part of the equation
