How To Choose The Right Carabiner For Your Needs
Not all carabiners are the same. The one you select should match the way you use it—climbing, work safety, or outdoor gear attachments. Choosing properly means understanding the differences in shape, gate design, size, weight, and strength.
Shape affects performance and use-case.
Asymmetric D-Shaped carabiners are lightweight and strong, with large gate openings for easier clipping. They’re slightly smaller on one end and dominate most gear racks. They have less internal space than oval or standard D shapes.
D-shaped models direct force to the stronger side, making even small ones very strong. A good all-purpose choice, they’re more compact than asymmetric D types but with a smaller gate opening
Pear-shaped carabiners, often labeled HMS, have wide tops suited to belaying and rappelling. Their large gate openings work well with ropes and knots. They are heavier and more costly than D types.
Oval carabiners are symmetrical and versatile, offering consistent load distribution. They’re great for aid climbing and gear racking, though less strong and heavier than newer designs.
Gate type determines how you clip and how secure the carabiner stays.
- Straight gates are common for general use, gear racking, and quickdraws. Durable and easy to use, some feature a keylock design to avoid snags.
- Bent gates are shaped for easier rope clipping, usually found on the rope-end of quickdraws. They’re reliable and often include a snag-free keylock nose.
- Wire gates are lighter due to fewer parts and resist freezing in wet, cold environments. Despite appearances, most are as strong as solid gates. Their low mass also helps reduce the chance of gate lash.
- Locking carabiners secure the gate with either a manual screw or auto-lock mechanism. They are heavier but essential for use with belay or rappel devices and critical anchors.
- Carabiner’s size and strength are just as important as shape and gate.
Larger ones are easier to handle and offer more space for gear. Smaller models are lighter but may have limited gate clearance. Gate open clearance affects how easy it is to clip; less space can make gear handling awkward. Always check the kN rating—a number indicating how much force the carabiner can withstand. Climbing-rated models are typically marked at 20kN or higher.
