Carabiners come in all shapes and sizes, and every one of them has a unique purpose. So many climbing companies produce them, and it can be hard to tell the difference from one brand's pear biner to the next. On the other hand, many companies are throwing all kinds of innovative ideas at the wall. We decided to take a survey of the current state of carabiner innovations, and found the 24 you see below. Some of them are mild improvements on existing technologies. Some of them are proven designs that have stuck around. A few of them are so different that they don't even look like carabiners (see: Kong Frog). We've compiled our findings without judgement, and included the intended benefits each provides.

Note: Many of these features are available on different carabiners, with different locking mechanisms, and even by different brands. These just happen to be the random ones we decided to showcase.

Anti-Cross Loading Innovations

DMM Rhino

DMMrhino480

Weight: 72g
Innovation: Intended as a belay biner, the thick protrusion extending from the top of the spine will prevent most assisted-braking belay devices from sliding out of alignment and crossloading the carabiner. The attachment point of the belay device won't fit over the Rhino's "horn."

DMM Belay Master 2

DMMBelayMaster480

Weight: 93g
Innovation: A rotating nylon clip swivels from the spine and closes over the gate, locking it shut, and securing the carabiner in the proper orientation for belaying. As an added safety measure, the nylon clip can only be closed when the screw-gate is in the locked position, and it also covers the screw-gate mechanism to prevent anything from unscrewing it.

Black Diamond Gridlock

BlackDiamondGridlock480

Weight: 76g
Innovation: An arm extends off the bottom of the gate to hold the carabiner in proper orientation when belaying and prevents crossloading. The gate must be opened twice to attach or detach anything in the bottom compartment, providing an extra level of security.

Metolius Gatekeeper

MetoliusGatekeeper480

Weight: 70g
Innovation: A two-pronged approach against cross-loading. The gatekeeper has both a second gate to secure it in the proper orientation on your harness, and a widened spine to prevent assisted-braking belay devices from sliding out of place.

Gate Innovations

DMM Shield

DMMShield480

Weight: 35g
Innovation: The wiregate twists into nose of this carabiner, functioning like a wiregate with the snag-free benefits of a keylock nose carabiner. Link: DMM Shield

Black Diamond Hoodwire

BlackDiamondHoodwire480

Weight: 37g
Innovation: A stainless steel hood surrounds the gate closure of this carabiner, allowing it to function like a wiregate with the snag-free benefits of a keylock nose carabiner.
Link: Black Diamond Hoodwire

Omega Pacific Lava Infinity Wiregate

OmegaPacificLava480

Weight: 34g
Innovation: Features a gate that’s pinched in the middle to make it less likely to open accidentally when dragging across rock, less likely to get tangled on your harness, and easy to clip.
Link: Omega Pacific Lava Infinity Wiregate

Omega Pacific Jake Keylock Quik-Lok

OmegaPacificJake480

Weight: 99g
Innovation: The gate on this carabiner opens at an angle providing a larger opening.
Link: Omega Pacific Jake Keylock Quik-Lok

Petzl Ange L

PetzlAngeL480

Weight: 34g
Innovation: A unique gate design splits the difference between wire and solid gates. The single pin-style gate provides for light weight and a snag free nose. The narrow gate is somewhat shielded from rubbing against the rock.

Rock Exotica Bi-Wire

RockExoticaBiwire480

Weight: 67g
Innovation: A twin wire-gate design provides extra security (think opposite and opposed by default), while remaining easier to clip than a traditional locking biner.
Link: Rock Exotica Bi-Wire

Grivel Plume K3G

GrivelPlume480

Weight: 39g
Innovation: A twin wire-gate design provides extra security (think opposite and opposed by default), while remaining easier to clip than a traditional locking biner. The wiregates cross through each other to facilitate easy clipping.
Link: Grivel Plume K3G

Grivel Mega K6G

GrivelMega480

Weight: 82g
Innovation: A twin straight-gate design provides extra security (think opposite and opposed by default), while remaining easier to clip than a traditional locking biner.
Link: Grivel Mega K6G

Grivel Sigma K8G

GrivelSigma480

Weight: 57g
Innovation: The twin-gate system in this biner employs one straight-gate and one wiregate to provide extra security (think opposite and opposed by default), while remaining easier to clip than a traditional locking biner. As you can see, Grivel makes their twin-gate carabiners in any combination of straight and wiregate you desire.
Link: Grivel Sigma K8G

Auto-Locking Innovations

Black Diamond Magnetron Rocklock

BlackDiamondRockLock480

Weight: 87g
Innovation: An auto-locking gate system that employs the use of magnets. When in the closed position, two magnetic pins pull themselves into a a steel plate on the nose, locking the carabiner. This creates a locker that's secure, but also easy to operate with one hand.
Link: Black Diamond Magnetron Rocklock

Edelrid Strike Slider

EdelridStrikeslider480

Weight: 62g
Innovation: An auto-locking gate system that employs a small slider on the outside of the gate to open. This creates a locking carabiner that's secure, but also easy to operate with one finger.
Link: Edelrid Strike Slider

Rock Exotica RockO Orca

RockExoticaOrca480

Weight: 80g
Innovation: This auto-locking carabiner is interesting for it's unlocking method. Most brands produce twist-lock gates. The Orca is unique because the twist lock can be set to stay in the unlocked position, keeping it ready to go without any difficult one-handed twisting.
Link: Rock Exotica RockO Orca

Misc Innovations

DMM Revolver

DMMrevoler480

Weight: 51g
Innovation: Features a pulley that's integrated into the rope-side of the carabiner. This can be used as the rope-side carabiner in a quickdraw to reduce rope drag on a wandery route, or it can be used as a standalone pulley for hauling systems.
Link: DMM Revolver

Edelrid 19 G

Edelrid19G480

Weight: 19g
Innovation: While it does not feature any interesting new mechanical mechanisms, the Edelrid 19 G is notable because it's the lightest full-strength carabiner on the market at 19g. It maintains a major axis strength of 20kN, minor axis strength of 7kN, and open-gate strength of 7kN.
Link: Edelrid 19 G

Mad Rock Trigger Wire

MAdRockTriggerWire480

Weight: 38g
Innovation: A spring loaded arm extends off the spine to hold it in the open position. When pressed, the gate will slide off the arm and pop closed. Used for stick-clipping or to make desperate clips a little easier.
Link: Mad Rock Trigger Wire

Petzl Freino

PetzlFreino480

Weight: 85g
Innovation: An extra wiregate spur on the spine of the carabiner can be hooked with the rope, allowing for extra friction and control on rappels. Link: Petzl Freino

Stubai HMS 3D

Stubai3D480

Weight: 95g
Innovation: Unique 3D design allows the gate to open away from the spine, allowing for greater clearance. Also orients itself to keep the rope from running across the rock-face.
Link: Stubai HMS 3D

Kong Ergo Wire Double Gate

KongDoubleGate480

Weight: 70g
Innovation: Generally intended for via ferrata and adventure park use, this carabiner features an extra gate along the top. When loaded, the gate will lock into a position that prevents the primary gate from opening, providing an extra level of security.
Link: Kong Ergo Wire Double Gate

Kong Frog

KongFrog480

Weight:70g
Innovation: This exotic looking “carabiner” is designed to be used on the bolt end of a quickdraw. When unlocked, pressing the opening against a bolt will trigger the locking mechanism, providing a secure attachment to the wall. It also facilitates long-range clips.
Link: Kong Frog

Bonus: Stubai Genius (No Longer in Production)

Innovation: The Stubai Genius provided for simple clipping, somewhat similar in idea to the Kong Frog or Mad Rock Trigger Wire. A second gate along the top of the carabiner holds the gate open until pressed, allowing the gate to spring shut. A unique shape at the bottom end secures webbing in place. This can be used on both ends of the quickdraw, as pulling the rope into place will also activate the gate. See the video for a demonstration.
