KKT 200 mounting ring with gasket

- made of galvanized steel sheet
- KKT is equipped with a single-edge seal
- it is attached to the pipe with screws or rivets
- the valve is secured by "screwing", by which the tabs on the plate valve fit into the threads in the mounting ring
- when installed in the pipe, the mounting rings are installed with rivets or screws, or with ceiling screws
- when installed in plasterboard, the cutouts are bent up and cut through the plasterboard. Securing is done by bending the cut-outs again with a tool so that the ring fits tightly on the ceiling.
