Cypher Iris HMS Locking Carabiner

For best results, pair with belay device or anchors.

It's always nice having Cypher's Iris HMS Locking Carabiner attached to your climbing harness's belay loop. Its round rope-bearing surface helps the rope flow smoothly for belaying or rappelling, and despite its compact size, the surface accommodates munter hitches. The Iris comes in a standard screwlock, an automatic twistlock, or a super secure three stage lock, and the carabiner features a keylock nose for snag-free convenience.

Is Cypher UIAA certified? I haven't seen anything indicating so.

Solid

As with some others I bought the auto twist lock as a belay biner. Its nice to know that as long as the belay device is loaded correctly, your biner is always locked and ready to go.

Perfect Belay Biner

For the price and the gate action and size - it can't really be beat as a belay biner!

Can't beat the price

3 stage locking biner for 13.95.... Mic Drop.

It's under 3oz, has a major axis strength of 28kn and once again is a 3 stage locker for 13.95. I use it as a belay biner or any spot an idiot could somehow mess up a screwgate locker. I really only buy locking biners that have screwgate mostly because of cost. Now I have a 3 stage and didn't spend almost $20.
