Kong became practically the only western manufacturer of stainless steel carabiners for industrial use. The customer was willing to pay a surplus of price, to have a product guaranteed and certified according to CE regulations, through destructive tests aimed at assessing the limit of breakage, resistance and corrosion. In those years the manufacturers of China and Taiwan were specialized in the production of non-certified carabiners, intended for uses that did not require particular technical requirements.
