Sealing and securing

Since 1838

Tradition and future

Since its foundation in 1838, the name S. Franzen und Söhne GmbH has stood for sealing and securing. Whereas locks and fittings were initially the focus of our product range, today we manufacture a wide range of plastic components for various industries and applications – from filigree individual parts and complex locking systems, from security devices for waste bins and weapons to interior parts for the automotive sector.

Leading positions

With our core expertise – the development and production of locking solutions – and our many decades of experience and comprehensive know-how, we have become the largest supplier of TSA locks throughout Europe. We are also one of the leading developers and manufacturers in the field of waste bin locks.
