Augie MedinaGreat Large Locker

Voted 5/5

This is a very nice large locker. Allows lots of room for Italian hitch operation for belaying and rappelling. A must have for canyoneering for occasions when you need lots of space within your locking ‘biner to do whatever. It may be just my imagination, but the locking sleeve on the manual locking system seems to work more smoothly than most. One quick twist with thumb or finger and you’re unlocked.

The lock on this carabiner is such a smooth twist, and so simple to use at those awkward belay stations. One of my favorite carabiners.

I've owned a pair of these with the ball-lock for over a decade. Practically every time I go out I have at least one on my harness. The biners look like they have endured years of use and they still work perfectly. The autolock is very easy to open one handed and it can swallow the largest knot or mass of rope in a single gulp.

The downside is that they're a bit heavy.

I've had a few opinionated climbers tell me how unsuitable the ball lock mechanism is in freezing temperatures, "Don't take that on Rainier, it'll ice up." So I always ask them, "Well, it hasn't happened on any of my trips to Rainier, Baker, or.... Has it happened to you?" The answer is always no. Somewhere in my climbing community is someone(s) with a megaphone and without the common sense to oil his biners. Or I'm just lucky.

Once a year I lube all my biners with Boeshield T-9, a 'corrosion shield & waterproof lubricant'. It works as good on my biners as it does on my bike chain, wonderfully.
