This symbol marks the items certified under the directive 89/686/EEC and related CE standards. By clicking over it, you can have the certification document. The majority of connectors (i.e. carabiners) with a locking device of the gate, are certified as per EN 362.

This symbol marks the connectors (i.e. carabiners) complying with the standards of the International Union of Alpine Associations (UIAA), that usually are more severe then CE norms.

The word "connector" is the name by which CE standardization identifies the devices that mountaineers usually call "carabiners" or "carbine hooks".

kN

Guaranteed loads are briefly marked on each item, and described in details into the attached instructions for use. The maximum loads, marked on connectors, are referred to these conditions:
major axis with closed gate (that is the usual condition), minor axis with closed gate, and finally major axis with open gate.

The loads marked with are those tolerated for repeated lifting with a safety ratio of 1:4 appr.

g  kg

Weights are generally  indicated in grams. The weight of the bigger items are indicated in kilograms.

mm

A measure in millimetres, and a symbol , indicates the main dimension of the item. For connectors this is the dimension A. The measure following the symbol indicates the maximum diameter of the rope that can get inside.

This icon indicates the carabiners that make use of the patented KeyLock System which avoid any snagging point that can entangle the rope. 

This icon indicates those items that are tested piece by piece.

These icons indicates the type of the sleeve (SC:screw - EX:express - AB:auto.block - TW:twist.lock) 

Warning: even though conform to all safety requirements, each device may be quite dangerous when used in an improper manner.

Specifications and colors, shown in these pages, may be modified at any time without notice.

AA 7075, 7010
ALUMINUM ALLOYS

These alloys are chosen in particular for mountaineering carabiners. They are a highly sophisticated material designed for aircraft structures with outstanding properties (for example, ultimate tensile strength 600 N/mm²) and extreme lightness.
 

AISI 316
STAINLESS STEEL

This alloy (with 20% chrome, 10% nickel, 2% molybdenum, no copper) is the most resistant to marine, chemical and environmental corrosion. Its use (in place more inexpensive varieties, very often defined as Stainless Steel) shows that no half measures have been adopted in terms of the quality of the finished products.

ISO 1338
NAVAL BRONZE

Among various types of brass or bronze, this is the specific alloy for use in marine environment (even propellers of big ships are made of this material). It is also extremely strong and should not be confused with the everyday brass. Kong uses this kind of material both for nautical outfits and for leather goods (buckles, &c).
