CRT TETHER RING
The Prostar CRT Tether Ring was designed as a safety device for Casing Running Tools (CRT). The Bolt-On Replaceable Anchors protect the Grease Port of the Sealed Bearing, with load rated / shock absorbing anchor points, allow the operator to secure the Tether Ring and CRT to the top drive below any connection that might back out. In the event that the CRT becomes disengaged from the top drive quill, the anchor points and safety sling ensures it does not fall to the rig floor. The safety slings are attached to the bail anchors on the Top Drive for a secure anchor point.
