Guided 60mm extension adapter (total length 80mm). Lightweight and durable. Compatible with general 5mm base diameter rod tips (Shimano, Daiwa, etc.). Thick pipe length: 30mm, thin pipe length: 60mm, overlap: 10mm, total length: 80mm, weight: approx. 2g. The inner diameter of the line guide is about 4mm, and the height is about 7mm. Since it is handmade, there may be slight variations. ★ Even with the same 5mm base diameter, there seems to be some difference in thickness depending on the manufacturer. If adjustment is necessary, please attach aluminum foil, etc. (The holes are made slightly wider and the shaft is made slightly thinner for easy adjustment.) ◆ If you purchase multiple sets, we will discount the shipping cost, so please comment in advance.
