Abstract
A technique enables anchoring of a tool in a wellbore. The technique utilizes one or more arms pivotably mounted to a structure for movement between a radially inward position and radially outward position that anchors the tool to a surrounding wall. A wedge component is positioned to selectively engage the arms. When relative axial movement is caused between the wedge component and the arms, the arms are pivoted to a desired radial position.
