CAMP Photon Screwgate Carabiner -

The Camp USA Photon Screw Gate Carabiner. Lightweight locking carabiners are hard to come by-especially full-size. The Photon Screw Gate accomplishes both brilliantly. The full-size design is easy to use even while wearing gloves making it a great choice for lightweight mountaineering and alpinism. The sharp nose profile easily slips into and out of webbing and old pins making it ideal for setting up snag-free anchors.

CAMP Photon Screwgate Carabiner Reviews:

Positive Reviews:

One unfailing axiom of climbing long routes, whether big walls or alpine pushes, is that you always seem to need one more locking carabiner. And ideally, the locker will be a keylock. Eliminating the notch in a carabiner, though it may seem insignificant, makes it much easier to remove a previously weighted clove hitch, work with tripled-up slings, and avoid other time-wasting frustrations. And as far as notch-less lockers are concerned, the Photon Screw Gate is simply the best.
At a scant 42 grams, the Photon weighs the same as many of the lightest wire gate carabiners of a decade ago. But with an aggressive knurling on the locking mechanism, and a true full-size gate opening, it is easy to manipulate in cold temps with gloves on or in situations when smaller lockers prove to be a complete pain.
Linking up routes in the Black Canyon of the Gunnison proved an ideal setting for the Photon Screw Gate. We'd packed a minimal rack and chose only smaller and lightweight lockers to compliment our Nano biners. With the constant need to build anchors, haul a bag, or clip a must-not-fail piece of gear, we had thrown a few extra Photon Screw Gates on our harnesses. Adding the extra weight is not where we went wrong. We didn’t add enough and still ended up running out a few times! They are so light we never noticed we had them until we needed them, but we were super psyched every time we clipped them. Next time, we plan to take at least one more each.

This locker lives in the bottom of my pack with my CAMP Alp 95 Harness,DMM Bugette Device, and Beal Rando 8mm Dry Rope. This is an ultralight setup that is always in the bottom of my ski pack. These biners have a great hand feel and are nice and compact. Did mention that they are light? If you are getting outfitted for a wall and need a lot of lockers these guys are great.

I use this with the DMM Bugette as my ski mountaineering belay setup. Works great with my 8mm rando line and due to its small size and light weight I'm way more inclined to have it with me in the event that I think I may need to rope up for ski descents or sections of climbing in the alpine. Easy one handed operation even with gloves on.

Lightweight Locker

This is my new favorite carabiner, and I love the locker version. It is light, and has a smooth action. This is awesome for alpine anchors or tag lines.

Neutral Reviews:

It's ultralight and compact.
1. Paints ropes badly.
2. Has too big screw nut made from too soft aluminium. Try to not to allow rock/nut contact.
3. High friction when used as a rope-end anchor binner.
I have 4 of these on my harness to build anchors on bolted routes and for "just a case" usage - it's always good to have 2 extra lockers.
