Product installation：

1. The installation length of air duct rubber compensator is selected by the user in the design. If it is not indicated when ordering, the supply shall be L=350mm.

2. The weight in the table is calculated according to the general installation length L=350mm.

3, there is a support frame in the middle of the joint, the support frame should be kept before installation, and all of it will be knocked off after the bolt is tightened, so as to ensure reasonable installation and make its physical and mechanical properties really play a role.
