opinion: PER CURIAM.
  The several petitions for rehearing are denied. So far as the contention by Delta Engineering Corporation (The Travelers Insurance Company) that payment to the plaintiff Scott of the judgment due by them to him and now affirmed by our opinion will render ineffectual their possible right to recover contribution or the like from Columbian Rope Company, the District Court on remand for the limited retrial shall be free to stay execution on that judgment on such terms and suitable security as required in its discretion to assure ulti- ' mate payment of the full amount of the judgment by Delta-Travelers to Scott with interest and costs. If, to preserve possible rights by Delta-Travelers against Columbian the plaintiff Scott is to be delayed in enjoying the fruits of the judgment heretofore affirmed in his favor, he is entitled to full security and protection.
  Denied.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "manufacturing". Your task is to determine what subcategory of business best describes this litigant.
