This can be accomplished many ways, using cams, springs, ramps, cables or other mechanisms. I suspect that there is a standard system available somewhere, but it would be quite easy to rig your own. I've personally built wipers on the bottom of doors, using rubber floormat material, either as a flap, or as a 'U' tacked onto one side or both. If set up properly, it will toggle (flip-flop) as the door goes back and forth, Like a windshield wiper. allen http://www.honeybeeworld.com :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
