What are oval carabiners used for?
Oval carabiners have smooth, uniform top and bottom curves to limit load shifting. They offer more gear-holding capacity than D-shape carabiners and their symmetry permits them to be used for carabiner-brake rappels.

What is an HMS locking carabiner?
Large screw gate carabiner designed for belaying and rappelling with either a Munter hitch or standard belay device. Keylocking closure eliminates snagging.
How do I unscrew a stuck carabiner?
The easiest way to unlock most stuck carabiners is by trying to unscrew the gate while putting weight into it. Sometimes you can simply pull the carabiner apart with your hands (applying force in line with the spine) while another person tries unscrewing it.
Why are carabiners so strong?
The design of a symmetrical or “D” shaped carabiner automatically aligns rope and attached runners to the spine of the carabiner. This is where the greatest strength lies in a carabiner, and is why it’s the most common design.
What are the four 4 different shapes of carabiners?
Different carabiner shapes
- D. Positioning of the load in the strongest axis, closest to the spine side of the frame.
- Oval. Symmetric shape for even loading (devices with a large attachment hole, pulleys…).
- Pear. High capacity, for connecting multiple items or bulky items.
- Wide opening carabiner.
Are Petzl carabiners good?
The Bottom Line. The Petzl Attache is the best locking carabiner on the market. It’s lightweight, well-designed, and very versatile. If I were forced to pick only one locking carabiner to use for the rest of my life, this would be it.
What’s the strongest carabiner?
D-Shaped Carabiners: D-shaped carabiners are considered to be the strongest and most durable on the market. They have a smaller gate opening than other shapes, but they still have a larger gate than oval carabiners. They are fairly affordable and excellent for a wide range of climbing exercises.
What is a Type H carabiner?
Type H (HMS) HMS carabiners have a curved shape making them suitable for a range of applications. They are often used with belay plates or for use as connectors at anchors. They come in different sizes and it pays to consider the best size for the intended application.
What does 22 kN mean?
Slings and similar equipment have rating in the range of 22kN (Kilo Newtons)to as high as 30 or so. Some Metal Carabiner can be as rated as high as 50 kN. A kN is around 220 lbs so a 23kN gear is rated at around 5060 lbs.
How much weight can a 27 kN carabiner hold?
As you can imagine, an aluminum pin of that size can not offer a comparable load rating vs. the spine of the entire carabiner. Don’t get us wrong, 8 to 9 kN is still almost 2000 lbs. of force that the pin can take, but wouldn’t you feel safer knowing you were protected by 27 kN (6000+ lbs.).
