    Great Little Carabiner

    • Familiarity: I've used it several times

    Super lightweight carabiner! I use mine with my PAS. It adds minimal weight to a harness setup and is small as well. Locking screwgate functions very smoothly. Will definitely be purchasing more of these in the future!!

    Best Price for an Awesome Locker

    • Familiarity: I've used it several times

    These are easily my favorite locking biners. They are slightly smaller and lock within a couple twists. Definitely recommend these as a great locking carabiner thats very simple to use.

    Nice Locking Biner

      I got this for my self anchoring sling and it's perfect. It's smaller in size and the nose is thin, as opposed to rounded, so it fits in those tight spots that can form when you're atop a route at the chains.

      Hang Tight

      • Familiarity: I've used it several times

      I just bought this because it was cheap and seemed reputable. Best believe this product is great!! Super light weight, especially for aluminum. Screw gate opens and closes with ease and quickness. And slick profile with great color scheme!

      The Quick Screw

      • Familiarity: I've used it once or twice and have initial impressions

      This is a lot like the DMM Shadow and Petzl Spirit locker offset D's. I've long used the Spirit and could easily see putting this in the rack instead. This isn't an H-frame like the other two, but it's close in weight and profile.

      Here are the picky details, since climbers have a right to be picky: this is a little narrower than the Spirit and the gate spring is a bit softer. But the biggest difference is the screw: aggressive grip here, and I can spin it shut in 2 turns (vs 4 for the Spirit and 5 for the Shadow).


      • Familiarity: I've used it several times

      Very sleek looking and feeling carabiners. I like how thin they are, it makes putting them through chains or a cluttered anchor a little easier. They're small though, so they wouldn't be my first choice for a master-point.
