Insulated round duct for traffic safety

This Ductmate insulated round duct is built for facility and traffic safety installations. It fits round ductwork with a diameter between 33 in and 36 in. The galvanised steel construction includes a sandwich-style insulation layer. The unit is supplied new and meets SMACNA standards.

Sustained thermal performance up to 200 °F

The assembly is rated for continuous exposure up to 200 Degrees F max without degradation of the insulation bond. Galvanised steel resists corrosion in outdoor environments. The sandwich construction maintains thermal integrity over long duty cycles. No hinges are fitted, so the door remains fixed during vibration.

The rectangular door measures 16 1/2 in wide by 12 3/8 in high. Installation requires a rough opening of 15 3/4 in width and 11 7/16 in height. Verify these dimensions against the penetration before ordering. This duct is not suited to smaller or larger duct diameters.
