The typical electrical garage door opener is made up of power unit which has the electric motor. The power unit attaches to a course.

Lately another kind of opener, referred to as the jackshaft opener, has become more popular. This fashion of opener includes a motor that transfers the door and attaches to the side of the torsion stick down and up by just spinning the stick. These openers need several additional parts to work for residential use. These have the edge that they free up ceiling space that railing and an average opener would dwell.
