Butler’s two-rail design has a capacity of 500 lb. with an optional lifting capacity of 750 lbs., making it our favorite IPL to install. There is no need to modify the walls because the rails mount on the landings. It is powered by standard 110V house current, but has a battery backup that will power the lift up and down as much as 15 times in the event of a power failure.
