Chain Drive KS15 24 V S12

The new heavy-duty chain drive KS15 sets standards in performance, handling and design. It has never been easier to move very large and heavy windows in the roof area.

With a concentrated force of 1500 N, the KS15 even moves very large and heavy windows safely and reliably.
Large opening elements reduce the number of necessary smoke extraction openings, therefore ensuring economical compliance with fire protection requirements.
Our project planning team will be happy to support you.
