Thanks for the heads up Majid.

I much prefer the Anthron 'Double Stop' descender to the Petzl device which I find a weak design at best.

Joe thanks for showing the Anthron

How does the rope attach to the Anthron?

Do you have to take the device off the biner to open it?

Also what's this mean?

"Double stop action brings you to a complete stop in both the 'SQUEEZE' and 'RELEASE' position"

Tell me what you think are it's quirks and what you feel is it's strong points ie: action, is it smooth with heavy load on it, the lever stuff like that.

Thanks ...

Werner, the principle difference is the Anthron device has fewer moving parts, doesn't 'open', and has the double stop capability. I consider it structurally more sound and easier to use. You don't have to remove the biner in the picture to thread or unthread the device. It's quite a smart design.

Thanks so much for that Joe.

Now I see how it works. The web site where the Anthron was shown had very little detail of how it really functions and threads into the device.

I've used the Petzl stop for many many years during high angle rigging on film sets around the world with heavy camera equipment loads of 300 lbs of gear on it at times while repelling and the stop mechanism was mandatory.

The Petzl stop was not perfect and you did have to push hard at times with those heavy loads to get it to stop completely.
