How to install the door and window door frame sealing strip?
When installing the sealing strips for doors, windows and frame fans, push the rubber strips slowly into the notches in the correct position with a special roller, and at the same time squeeze the rubber strips down to make them fit into the notches. In order to prevent the elastic shrinkage of the rubber strip due to rolling, pay attention to retracting the two ends of the rubber strip to the middle when installing, and cut off the insertion slot after leaving some length.
