5.3 Reef says the pipes are 1-1/4 " Schedule 40 Steel. 1-1/4" nominal pipe size is actually 1.66" OD and that matches the CAD files released.
5.4.1 Cage says the pipes are steel 1-3/8" Schedule 40, a nominal size that doesn’t show up in my charts. The CAD files show an OD of 1.315", that matches 1" nominal pipe size. Can anybody confirm that the pipes for the cages are 1" Schedule 40?
Questions about other officially-provided materials have been addressed in the past. E.g. in 2024 (PDF), Q71 and Q74 addressed discrepancies between the team drawings and the cut list.
