Abstract
A downhole catch assembly includes a catch stem having a radial protrusion to provide a landing shoulder and a catcher sub having a longitudinal central axis and the radial protrusion of the catch stem located within the catcher sub. A landing ledge extends radially inward inside the catcher sub for engagement with the landing shoulder of the catch stem. An installation bore angled relative to the longitudinal central axis enters a bottom terminus of the catcher sub offset relative to radial center of the catcher sub. The installation bore extends into the catcher sub above the landing ledge to facilitate installing the catch stem into the catcher sub.
