Thank you for viewing. This is a conversion adapter for the screw diameter of landing nets. It allows you to connect a landing net (landing net frame) with an M8mm size screw, common in overseas manufacturers, to a landing pole with a W1/2 (inch screw, diameter 12.7mm) size screw, common in domestic manufacturers. This is the same as the inch screw W1/2, 4-bu, 12-thread pitch used by many domestic manufacturers (SHIMANO, DAIWA, PROX, etc.). [Specifications] Male protrusion: W1/2 (inch screw, approx. 12.7mm diameter) Female receptacle: M8mm Overall length: approx. 30mm Width: approx. 16mm Material: Aluminum All items are inspected before shipping to ensure they are free from defects that would affect use.
