Cassettes made of aluminum-plastic composite panels are placed on the facade substructure using special fastening hooks, which are fixed with pop-rivets to the side flanges of the cassette. Fastening hooks are mounted on cassette holders, which are pre-installed on the bearing vertical profile.
There are different modifications for the fastening hooks and holders to be used on L-shaped and A-shaped profiles. Cassette holders for A-shaped profiles have additional adjustment, which allows to mount the holder regardless of the position of the cassette across the entire width of the vertical profile.
A gripper is additionally used for fastening horizontally oriented cassettes made of aluminum-plastic composite panels. It is installed on the upper / lower flanges of the cassettes, thereby tying them and increasing the carrying capacity of the cassette.
