Blocking Spring SecuFix
Components for roller shutters
Perfect for drives that switch off to torque
Since 2019, blocking springs have been manufactured at SELVE and are extremely popular.
With the blocking spring "SecuFix", the range of mechanical components is conclusively completed. SecuFix can demonstrate its high stability, especially in connection with torque-based switching off roller shutter drives. The unique, patented twist lock ensures quick assembly. SecuFix is available for different box sizes in different lengths.
SecuFix has been optimized for the use with octagonal shaft SW 60, but also fits to shafts SW 40 and SW 50. SecuFix can only be used in conjunction with a roller shutter drive or crank gear.
