An adjustable 45-degree elbow gets crimped and frozen
Adjustable gores should rotate smoothly. If the seams are crimped, loosen and reset the gores before locking the angle, or replace the damaged fitting if it cannot hold shape.
Do not crush adjustable gore seams so tight that the elbow loses diameter or freezes out of shape.
Check
Check whether the gore seams still rotate smoothly.
Look for ovalized throat, crushed seams, or sharp internal lips.
Reset the angle with a level or angle finder.
Lock the gores only after the fitting holds shape.
Seal the seams after the fitting is mechanically correct.

Say this to your foreman
The adjustable 45 at [location] got crimped while setting the gores and the throat is losing shape. I can reset it if it opens cleanly, or replace it if the seam is damaged. Which way do you want it handled?
