Driver with hook 1500 mm

Description:

The crank is a handle with a hook at the end, 1.5 m long. The hook is inserted into the loop of the cardan installed in the protective box, and by turning the handle the shutter curtain is raised and lowered manually. It is used in roller shutter systems that use a Manual series motor as the curtain-lifting mechanism, which is housed inside the shaft, while the roller shutter is operated by a switch or a remote control. This emergency opening system is installed for cases where there is a potential risk of a power outage in the room. Using this handle, you can perform an emergency opening of the shutter.
