Thank you for viewing. This is a conversion adapter for the screw diameter of landing nets. It allows you to connect a landing pole with an M8mm size screw, common in overseas manufacturers, to a landing net frame with a W1/2 (inch thread, 12.7mm diameter) size screw, common in domestic manufacturers. This is the same as the inch thread W1/2, 4-bu, 12-thread pitch used by many domestic manufacturers (SHIMANO, DAIWA, PROX, etc.). [Specifications] Male protrusion: M8mm Female receptacle: W1/2 (inch thread, approx. 12.7mm diameter) Overall length: approx. 31.8mm Width: approx. 16.6mm Material: Aluminum All items are inspected before shipping to ensure they are free from defects that would affect their use.
