Dale, they are too cheap for that. There are three pianos at Rutgers chained to the wall in class rooms where they dented kto wander all over the building. Get BIG eye hooks and drill a hole into the wall with a masonery bit, or into a stud if the walls are wood framed. Get some 5 minute epoxy and put some on the screw and the rest into the hole. Turn the eye hook into the wall and wrap a length of chain around a post and pad lock it in place, useing just enough slack you can get your hands in their to unlock the sucker when the time somes. Worked for me for sever years. Newton
