The discrepancy between my sketch and PSI drawing LIGO-D961094-v2 lies in the depth of the shell of the 84" doors. In November 2020, Eddie (at Chandra's request) updated the depth of the shells for all 84" HAM doors in Solidworks from 19.63 to 17.63 to match the as-built PSI door drawing D970427-v1. HAM shells in this PSI drawing D961094 are 19.63" (incorrect).
