Threaded support made of zamak in black finish for inverted closing hook of single-leaf shutter.
This support is attached , one to the top and another to the bottom of the shutter. When the Spanisheta rotates the bar, it activates the hook, holding it in the support to keep the shutter closed.
Installation is simple , consisting of two lag bolts anchored to the wall closest to the hook.
You must put the hooks in the reverse of the standard . They are not special hooks but must be mounted upside down.
