The gravity lock system from SUDHAUS protects different containers from unauthorised access. The waste bin lock helps users and removers. Only your own rubbish fills the dustbin and the lock will open automatically when being emptied into the waste truck. Raccoons or other animals cannot get into the bin. After the emptiing process, the lock closes automatically so that unwelcome rubbish does not get a chance. Unauthorised use excluded. Automatic opening included.
