400mm EPNF Spiral Duct Termination Grills are female-ended fittings to be inserted directly onto round Spiral ducts.
The 12.7x12.7mm mesh installed at the termination end secures the air exhaust against birds, large insects, leaves or debris. This is the simplest form of ductwork termination with a minimum air intake/exhaust flow resistance.
