How do I connect TDC/Ductmate duct sections?

Rectangular Duct Assembly: TDC / Ductmate / FlangesPolished core starter — connector/detail check

Support both duct sections, clean the flange faces, apply gasket per the approved detail, bring the flanges together square, start corners/bolts/cleats around the whole joint, then tighten evenly. Do not use one corner to pull a twisted joint together.

Field checklist

Support both pieces before pulling the joint together
Gasket in the right place with no gaps at corners
Corners/bolts/cleats started before final tightening
Flanges square, not twisted or forced

Ask foreman

I’m connecting TDC/Ductmate duct sections. Can you confirm the gasket path, corner clips, cleats/bolts, and tightening sequence before I lock this joint in?

Do not

Do not pull a bad alignment together with one bolt or one corner. Do not skip gasket/corners because the duct is already in the air.

Why it matters

A sloppy flanged joint can leak, twist, crush gasket, fight insulation, and fail pressure testing or inspection.
