Dear Aleksandra,
Good morning,
Thank you very much for your vigorous support and collaboration,
You’re right,Jinmao’s wedge structure is contains 1ribs on the bottom of position,
Sample 1: mounted with Domex wedge with 2ribs
Sample 2: mounted with jinmao wedge 1ribs
At the same time,We will put in several stick of single threads rolled stem and new wedge nut,
With single thread rolled stem: 35laps for closing and opening,
It’s understandable,
Best regards
Tom |
