According to Baidu Love Purchasing, there are two ways for canvas soft connection and louver connection:

1. directly installed on the air duct. Open a rectangular notch about 2mm larger than the tuyere size on the air duct, then draw a long notch on the side and fix it on the air duct with screws. Note that the batten should not be too outside or too inside, and it is best to be flush with the notch, and then fix the louver on the batten with screws, paying attention to being parallel to the edge of the air duct.

2. The blinds are flush with the ceiling. But there is a soft connection in the middle that needs to be connected with the air duct, that is to say, the air duct is higher than the ceiling, and then the louver is connected with a flange that hangs the soft connection.

Canvas soft joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. It consists of inner and outer rubber, polyester cord and traveler, and then it is vulcanized at high temperature and combined with metal flange or parallel joint with loose sleeve.
