Rockwood 491.26D Satin Chrome Automatic Door Holder with Stop has a floor-mounted strike for use with doors that have 1/2" or less of clearance under the door and includes fasteners to attach the holder to a solid wood door and the strike to a concrete floor. Door holder's roller catch automatically latches to the strike to hold the door open and releases by a gentle pull. Floor-mounted strike also acts as a stop to protect adjacent walls.
