Model STA Tubing Anchor/Catchers are used to allow placement of tubing in tension. Vertical tubing movement is prevented which in turn lessens sucker rod tubing wear.
Their small o.d. and large i.d. permits larger volume production capacities. These fully retrievable tools can be easily adjusted for emergency release by adding or removing shear pins. They are available for 4 1/2" through 7 5/8" casing.
Features:
  • Sets securely in any hardness casing, including premium grades
  • Large bore
  • Small OD
  • Model "R" right hand release or emergency shear release, Model "L" left hand release or emergency shear release
  • Easy adjusted release from 5,000 lbs to 60,000 lbs
  • Drag blocks rather than drag springs
