The 9 Best Petzl Screw Lock Carabiners (2023 reviews)

The features department is where petzl oxan carabiner truly manages to shine. It is a dandy steel carabiner. Petzl's keylock system helps avoid accidentally snagging your carabiner on your gear. It is made of steel and much stronger than aluminum. It is available in two locking systems. It allows for optimal positioning, reduces risk of a catch point, and facilitates easy rotation.

Unlike aluminum carabiners, this can hold quite a bit cross-loaded and gate-open. It is designed for use in difficult environments and is particularly suitable for setting up anchors for connecting to metal structures. The wide bend radius means this is easy to tie a line on.

Best For belay device: Petzl lightest Locking Carabiner

Buy on Amazon

If you often find yourself confused about appropriate and satisfactory carabiner, this product is your solution. The screw fastener tightens as expected to hold in the opened and closed positions. It is designed for better rope glide and positioning of the belay device. It provides a visual warning when the screwgate carabiner is unlocked. The cross section is pretty small and the rope will run along one single path (the groove in the top), so it's a poor choice for a belay biner with an ATC as it'll wear down much quicker than most lockers. It's also got a nice rope surface, nice action, and a shape that makes it perfect for creating a quickdraw or alpine draw with a locker on one end.

The thin design allows you to hook through climbing shoes loops. The fact that it's so small means you can clip it to chains and bolt hangers with room to spare, leaving the carabiner free to rotate and reducing risk that it might stuck or dangerous cross loaded on a bolt.
