When did the use of mechanized openers for garage doors begin to gain traction?
Answer
In the 1920s
Shortly after the sectional door design became standardized in 1921, inventors began developing mechanical openers. These early systems, which used electric motors and belts or chains, were introduced to assist with the lifting process. While initially rudimentary and sometimes retrofitted onto manual doors, these mechanisms paved the way for the integrated automated openers seen in later decades.
