Galvanised Spiral Duct End Cap (250mm – 630mm)

Galvanised Spiral Duct End Cap

A galvanised steel end cap for closing off the open end of round spiral ductwork – the end of a main run, a spare branch or a future connection point. It slides into the duct for a tight fit and can be fixed with self-tapping screws or rivets, then sealed with duct tape or mastic for an airtight finish.
