发明名称 Two piece carrier and balance assembly
摘要 A carrier and balance assembly for installation into the jamb channel of a window frame. The carrier and balance assembly are capable of being installed into the jamb channel optionally either as a single assembly or as two separate components. The two separate components are the carrier and a hanger-balance subassembly. The advantage of installing the carrier and balance assembly as two separate components is that such installation can occur after the assembly of the window frame and even after installation of the window into the wall of a building. Once the carrier and hanger-balance subassembly are separately installed in the jamb channel, they are then non-permanently locked together. Should any part of the carrier and balance assembly become damaged, replacement is performed by simply reversing the process described above without having to damage the jamb channel.
