A novel electric door opener for a garage, or equivalent structure, which uses a rail fixed at one end to a drive assembly and the other end to a mounting support, in which the drive assembly is mounted on the wall over the garage doorway with a pivotable mount, rather than the uniform practice wherein the drive assembly is suspended from the garage ceiling, thus significantly enhancing safety during installation and over the lifetime of the unit. In addition, the means whereby prior art rail type garage door openers, including their drive assemblies and overall mounting methods, are redesigned to reduce the invention to practice. The simplification of mounting hardware and process with this design makes it much easier and safer to install, remove, and replace an assembled rail type garage door opener, using only three removable pins.
