Rotating spring-latch hooks

They have a base set on fixed or C-shaped attachments to the chain, assembled together with a rotating spring-latch unit, with clicks at every 90°.  For medium-light loads, use the pressed steel wheel systems, while heavier loads should use double steel cam technology.

They can be equipped with a locking system in order to ensure the correct direction/orientation of the item during movement down in line, allowing rotation only where and when necessary.
