Rock Climbing Photo: Mad Rock biner?
Mad Rock biner?

Any clue what this, and what it's for?

Oh. I looked some more. It's called the Gemini and it's a belay carabiner. Seems like a terribly over-engineered solution to something as simple as belay device cross-loading, considering how simple the capture wires on other products are.

In most situations, I just don't actually worry that much about a cross-loaded belay biner. In no top-rope or single-pitch lead situation will the force on my belay biner even come close to the 7-9 kN cross-load rating. The only point I might worry about this, is if I'm catching a high-factor fall off the anchor in a multi-pitch situation. I try to avoid those for other reasons than belay biner cross-load, though.

Black Diamond Gridlock seems infinitely more elegant.

Honestly, it is pretty nice just 100% taking cross-loading out of the equation. I am a fan.

Wish it had a nicer top bar cross-section. I'll get one of these because it's goofy and I love gadgets, but for belaying with a tube device the best picks are the WC Ascent Lite Belay, and the Grivel Clepsydra, which both have nice big, round top bars. Noah Yetter

Man... That is one complex and over-engineered fix to what is barely a problem.

This is my go to solution for belay biner cross loading

I am not at all concerned about cross loading of belay biners. That said, all of my belay biners have some sort of anti cross load feature, not because I think it's a safety concern (I do not when it comes to belay biners) but because I am a control freak. I don't like my belay biners spinning around when a don't want them to, and I never want them to.

I'll probably get one and never use it... I like weird gear...
