Solid locker

Pros

Large basket

Good for belays and personal tethers

Cons

Scratching sound in the screw after some use

Familiarity

I’ve used it a ton

I primarily use these for belaying and for attaching myself to anchors. They're big enough to handle clove and munter hitches, and they work well with all the belay devices I've paired them with (ATC, ATC-Guide, Pilot, Pivot, GriGri 2).

They are big and heavy though, so I try to minimize the number of these that I carry on longer routes. Also I've noticed a strange scraping/squeaking sound with the screw on the gate, that has developed on all my carabiners after normal use. It doesn't appear to affect the integrity of the carabiner, but it can get annoying. This has not happened with other lockers that I own.

Its a locking carabiner, you can't go wrong with this one.

Big, good for belay !

Pros

Wide gate opening

Cons

Heavy

Familiarity

I’ve used it a ton

This is a very large carabiner and can handle every hitches and knots you can throw at it. Very good if you are using ropes on the thicker side. I find that the locking mechanism gets gritty and rattles alot over time. It is heavy but for the size it gives you I think the weight is acceptable.

There are some better options out there, I prefer the Petzl Attache over this one.

My belay biner!

by Alison Dennis on 09/24/2012

Pros

big without a crazy weight gain

smooth locking gate action

This biner is my permanent belay biner. It's fairly large ("Does your biner hang low? Does it wobble to and fro?..."), so it'll easily accommodate a munter or whatever else you might throw it's way. I only have one large locker on my rack, and this is it.

The gate action is somewhat slow (6 spins up) but gravity helps it the other way (4 spins down). No matter the orientation, I've never had an issue with it becoming unlocked, even after an aggressive belay.
