Spring shafts

• Spring shafts offer a good and inexpensive alternative to electric drive especially for small rolling grills and shutters (up to approx. 100 kg).
• There is a purely manual drive which does not require an electrical connection.
• Doors with spring shaft drives are very robust as well as quick and easy to use.
• To safeguard against unauthorised opening, there is a lock at hand height or in the end strip.
