Yesterday, BSC6 South door was pulled, after a couple rounds of chamber cleaning.
We installed the Support Tube 'Pillows' which fit under the Support Tubes in the chamber nozzles.  Once in place, the Scissors tables are used to lower the Support Tubes onto the pillows.  To lock them down, A cable goes around the Support Tube and shackles to a Bracket bolted to a chamber interior flange.  See photo, this is not tensioned up yet and there will be one on each corner.

Once the Exterior support structure is removed, further positioning constraint and bellows protection will be installed.
