What This Helps With
Apprentice sees a slip-and-drive/S-cleat joint and may not know which side gets the S, which side gets the drive, or why forcing it can rack the duct.
Apprentice words: slip and drive
Trade terms: S-slip, drive cleat, drive, slip
Check First
S-cleat on the correct side?
Drive cleat started square?
Duct ends matched without racking?
Joint seated before sealing?
What Not To Do
Use a slip that's shorter than the duct width
What can go wrong: Leaving drive ends un-bent
Better Foreman Question
This looks like slip-and-drive. Can you confirm S-cleat and drive orientation before I seat and seal it?
