Field check
Standard work. Do it right, keep moving.
Close back-to-back flanged fittings can run out of corner clearance. Align the faces, protect the gasket, and get approval before trimming or using alternate hardware.
['A tight S-offset can put two companion-flange corners so close together that the corner lips or brackets fight each other. Forcing the bolts can twist the fitting and open a leak path.', 'Loosen the line, square the faces, and verify what is actually overlapping. Minor corner cleanup may be acceptable if it does not weaken the flange or violate the shop standard, but get direction before grinding factory hardware.']
