Kinda neat but is it rated?
I've used this slider on a Grivel Evo axe for a couple of seasons and for the most part thinks it's a cleaver set up.
However, I'm curious if Grivel offers any weight rating on this? My assumption is not since it's partially plastic so you should be mindful of that when using the axe to back you up on a belay or 'secure yourself' on the slope since it's probably providing a false sense of security compared to a traditional piece of webbing or cord that a climber might use to connect their axe to their harness.
Backcountry.com - can you verify if the slider has any rating at all?
The Grivel Website makes these warnings with their Single and Double Springs: Attention: the double spring must never be used as a self belay for the climber or to belay a companion. Its strength is limited to 200kg.
The two small carabiners have a maximum resistance of 750kg and must never be used instead of normal carabiners when climbing or belaying.
But it doesn't have an comment on Easy Slider 2.0, which happens to be on the same tech sheet.
