Serial and revision scopeSpiral LH R1071643-0 revisionAA April 27 2017; L9.5-inch and S14-inch columns. ProductLH means low-headroom configuration, not motor hand. Confirm serial, hand as viewed from front, actual Object List dimensions and specific installed electrical schematic. CF/REF used instead of an identifier and height/width-made items remain configuration references; a REF quantity alone does not invalidate an exact printed number. No cross-family, reverse, transitive or replacement inference.
