Abstract
A pre-set inhibiting extrusion limiter has a segmented anti-extrusion ring with a plurality of anti-extrusion ring segments supported by a stepped cone frustum. Each ring segment is retained in a run-in condition by a compression spring retained by a retainer ring held in a retainer ring groove in the respective anti-extrusion ring segments. A push ring moves the respective anti-extrusion ring segments from the run-in condition to a packer-set condition in which the anti-extrusion ring segments abut a cone frustum step of the stepped cone frustum.
