Hardware for a lift glide door assembly and lift glide window assembly provides ease of opening with an operational opening assist that urges the door or window to an open position on operation of an opening handle by use of a cable drive system. A lock mechanism actuates a lock pin, blocks opening gear mechanisms from operating and extends a security bolt for locking. A guide blade is provided for assisting the door during opening or closing operations.
