20 ft cantilevered gate only need to be 31 feet long. Not 40 or more
It can be "free standing" or have roller wheel on the end if desired. Nylon wheels handle ice better for those times you get ice issues. Track on the ground one way for a slider but not needed for a true cantilever gate. Mighty mule gates brand makes more than a home owners quality product. light commercial openers in swing and slider are available, just often times not seen on web sites or local stores. Calling them direct or accessing their web site will help on this issue. Linear brand I think or a similer spelling is their commercial line. Several price ranges. All avaiable on their web site. Push button on a post, Key pad with multiple codes, and remote openers, magnetic sensors for opening or closing available for all of their products. Solar power get a bit bigger panel than you think you need. Most openers from these brands have room for two batteries if desired.
