Abstract
A portable hydraulic floor jack has a saddle member with an axial stem that is provided with an end collar having a flattened side surface. This permits the saddle member to be rotated to a singular orientation in which the flattened side surface of the end collar can bypass a locking pin that is permanently installed transversely of the receiving opening for the stem of the saddle member.
