The Salice DOUXHG Smove soft-closing door hardware for S series face frame hinges is simple to install. A screw at the back of the Smove allows the user to easily adjust the speed of the closing action. For door overlays of less than 1" mount the Smove in the upper corner on the hinge side of the opening. For doors with overlays greater than 1" mount the Smove on the hinge side of opening at the top for small doors or about 1/3 of the way down for larger doors.
