Low overhead clearance hazard at Xend
The path around the H2 BSC chamber to the back side of the vacuum envelope at EndX goes through and under the white steel frame for the SEI and SUS mating. See photo below. The overhead clearance is really low, about 5 to 5.5 feet. It can be and has been a real head buster. Especially hard to navigate with (often fogged) laser glasses, clean room garb etc. Mike Vargas added some red tape to both sides while I was picking myself up. We might consider dismantling it now or somehow rerouting the path to the back side.

I conked myself on this earlier in the week. Can we rotate the frame so that the lowest part is facing away from the clean room?
