EVB adjustable locking bolt

The adjustable locking bolt is used to lock the skylight dome / arc dome in the closed position. For use in mounting (e.g. BF and BG), in conjunction with the MHV mechanical locking device.

If the ventilation function for the pneumatic fitting is to be retrofitted, the EVB can also be replaced with a ventilation actuator using the SET-L extension set.

When a SHEV unit is closed and in ventilation mode, the hook engages with the bolt attached to the mounting bracket / ventilation actuator and is locked by spring force. When the SHEV fitting is opened, the hook is automatically released from the bolt; when it is closed, it automatically reengages with the bolt.
