AMERICAN DENKI’s main products are twist locking wiring devices.
If you put the plug in the receptacle and turn it to the right, it locks and becomes impossible to pull out. Therefore you can use the plug safely without feeling worried about it falling out of the receptacle.

We have been manufacturing and selling in Japan as a pioneer of this field for about 80 years. Now we are dealing with about 30 or more kinds of rated twist locking devises, corresponding to each standard (including JIS or NEMA) of 2-4 poles or 15-100 amp and IP65 waterproof performance.
