Abstract
Disclosed herein is a tubing string anchor for resisting angular rotation of the tubing string, as when undergoing pumping through the string. The anchor includes a plurality of anchoring members each rotatable about a fulcrum between a locking position and a non-locking position. The anchor housing has a groove formed between adjacent anchoring members through which a string may be run to access below the anchor when the anchor is installed.
