Steel and aluminum carabiner
Steel carabiners were born in the early 1800s dedicated to it’s use within the war and work fields, while the diffusion of the actual climbing carabiner started only after the Second World War. The beginning happened in Italy and France, where the production of mountain carabiners of new materials began: light aluminum alloy (ergal). Since then, it’s development has continued with the introduction of new shapes (oval, pear, asymmetric, etc) and some new details, such as an automatic snap gate (quick opening carabiner).
Within our slackline world the most commonly used carabiners are the oval shaped ones, where load forces are equally distributed between both sides. The carabiner can connect you TENSIONING DEVICES (pulleys, brakes, etc.) or it can be used in a primitive pulley system. Commonly integrated into slackline sport as well are the steel carabiners, because of its high strength and resistance to repeated stress movements, as well as the aluminium carabiner for its extreme leightweight.
Carabiners There are 10 products.
Is the oval carabiner better with or without a screw nut?
Carabiners can be divided into two main groups: carabiners with screw nut and without. The screw gate carabiner, once closed, prevents accidental opening of the gate. This avoids accidental situations like the lever that my open with movement, generating a risky situation or even breakage of the carabiner. A lever locked with a ring nut avoids this problem entirely.
The lighter, normal gate carabiner without screw is preferred in those cases where you are reasonably sure to not risk any accidental opening, or if occuring, the risk stays rather low.
It is used, for example, for the multiplier of a primitive system, or to connect other secondary gear to the pulley system, or as a simple key holder on your backpack or harness.
Keylock carabiner for slacklining
All Spider Slacklines contain the KEY-LOCK system (catch-free), which means the contact point between the carabiner gate and the body is completely smooth, without any hook for potential gate lever. The KEY-LOCK system avoids tangling up your webbing when opening or closingg the gate.
The carabiner keyring or material holder
We offer also a small carabiner keychain, called carabiner key ring, which is a good rigging gear holder but does not support a person's weight can't be used as protective personal equipment, but is very useful because of is light weight small pricep, and makes transport of gears more comfortable.
