I had this beautiful handset installed and noticed that the outside handle was loose. I took it apart and noticed that the coil spring had sprung and parts were completely loose. Resetting the spring was quite difficult with just two hands and needed to call my neighbor for assistance. He also has a tool to spread the brass ring washer that sits in a groove, holdng all of the parts together. I hope this works and there are no issues with this handset once I deliver and install the doors.
Great product that was perfect for the job.
