Stop collars
  
  Keep centralizers and other casing attachments in place on the casing.
  
  Available in hinged and slip-on styles and size from 2-3/8''- to 30''.
  
  Stop collars use set screws for increased holding force. The hinged design is for applications on upset tubing. These stop collars are available in slip-on for tight clearances and hinged for semi-tight clearances.
Hinged Bolted Stop Collars secure placement and limits travel on attachments to casing string. The stop collar uses a single draw bolt tightening mechanism with "hardened inserts" to grip the casing once tightened.
The specially designed dogs bite into the casing, which provides the stop collar's strong holding force. The recommended torque on the bolt is approximately 25 to 35ft-lb. When properly installed, the hinged stop collar can provide a holding force up to 40,000lb.
