CT RollNLock

I noticed a number of people using these for smaller diameter rope as a substitute for the Ropeman 2 that are used on larger diameter rope or even friction hitches for their lineman’s belt and tether. I came across Climbing Technologies YouTube page and saw where they were giving an overview of this device. Something that was a little surprising to me was that in the vertical down locking position which most saddle hunters would use it is rated to a max of 4kN or ~900lbf.

I would just urge y’all to back this up when tethered in or use it as the manufacturer intends which is a positioning aid (which should always be backed up).

This may have already been brought up but I thought I’d throw it out there.

I think that type of device, a rope clamp, is only tested to 4kN to pass to get certified, it is definitely stronger. Richard Mumford has used it while break testing adjustable bridges, he has many informational videos on YouTube.

All ascenders of that type (eg. Ropeman 1, Kong Duck) will sever the rope or at least it's sheath at about 4kn.

Yeah definitely stronger than 4kn but the problem is desheathing of your rope. Hard enough drop and it will cut your tether in half. I don't get why guys want to use these on their tethers. They are a game changer on a lineman’s belt. I usually never move my tether to adjust, just my bridge. Sterling sewn autoblocks are a fraction of the cost and intended to act as a fall arrest.
