Once we got the go ahead from Betsy, we installed the -Y door on HAM1 (particle counts were 0/0/0 in the cleanroom). Initially no issues, but as we brought the door close to the flange, the inner o-ring jumped out of the groove. We had to move the door back from the flange and re-seat the o-ring. 

With the door tacked with ~8 bolts, we removed the blank on the A2F3 port so they could check beam alignment on the viewport to be installed.

2nd time was the charm, the o-ring stayed in place so we installed and tightened all bolts. The gap closed up evenly. +Y door still to be installed.
