Thank you very much for viewing. This is a conversion adapter for the screw diameter of a landing net. It allows you to connect an M8mm size landing net (landing net frame), common with overseas manufacturers, to a W1/2 (inch screw, 12.7mm diameter) size landing net handle (landing pole), common with domestic manufacturers. It is the same as the W1/2 4-minute 12-thread inch screw used by many domestic manufacturers (SHIMANO, DAIWA, PROX, etc.). 【Specifications】 Male: W1/2 (inch screw, approx. 12.7mm diameter) Female: M8mm Total length: approx. 30mm Width: approx. 16mm Material: Aluminum We inspect all items and will send products that have no problems in use, but there may be minor scratches.
