I have a pole barn that has two garage style doors 14' wide x 14' tall. These are light-duty doors. Is there any way I can put an opener on them so that I can open them automatically? I checked around and most want me to buy a "commercial grade" door opener for $1K+. I'm thinking I can buy any homeowner style unit and just buy extensions for it so that it will fully operate the door. FWIW these doors require very little force to open and close. Not much more than my 8' door at home.
