Has anyone ever added an extension to a liftmaster garage door opener model 8605/ If so where did you get the ext. at.
I nee to add to mine, it is for a 7' door and i installed an 8' door Got a ext kit 7708Cb which is a square tube and mine is a t- shape rail. Liftmaster and the place where i got it says it will work, but how do you hook a square tube to a t-rail
