D Carabiners
D Carabiners are made of steel.
They come in symmetrical and asymmetrical models.
Symmetrical D Carabiners are roomier and pressure-resistant. They are ideal for top and lead rope climbing.
Asymmetrical D Carabiners are narrower. They are ideal for belaying and top roping.
Oval Carabiners
Oval Carabiners made of steel.
They are inexpensive and less durable than D Carabiners.
Their even shape equalizes pressure and helps manage load shifting.
They are difficult to clip in foot loops and pegs.
They are ideal for big wall and aid climbing, and pulley hauling.
Locking Carabiners
Locking Carabiners are made of steel.
They have locking systems that stop the gates from opening unintentionally.
They are ideal for rappelling, belaying, and locking gear.
They come in oval, symmetrical, and asymmetrical shapes.
Wire Carabiners
Wire Carabiners are made of extra thin steel.
They are roomier with larger and snag-resistant wire gate openings.
They do not have locking mechanisms.
They have an approximate open strength of 10kN and a closed strength of 25kN.
Straight Carabiners
Straight Carabiners are made of aluminum alloy.
They are extremely lightweight.
They have wide openings ideal for lead climbing.
They have angled noses for easy clipping.
Bent Carabiners
Bent Carabiners are made of anodized steel or aluminum alloy.
They have concave curves that allow for more rope room and easier clipping.
Gear, rope, and other loads must be attached properly to prevent whiplash unclipping.
They are ideal for sport and lead climbing.
