If the eyelet is circular it is called wakakegane 輪掛金, and if oblong, it is called saokakegane 竿掛金. The part which is nailed to the stile of a door to receive the hook is called uketsubo 受壷. There are many kinds of kakegane. The following are examples of those used especially in tea ceremony rooms *chashitsu 茶室:
1 Rojizai tsurikan 炉自在釣鐶. An assemblage for hanging a kettle composed of a metal ring, circular and square washers, maruza 丸座; and kakuza 角座, and a pin *sen 栓.
