Ductmate insulated curved access doors offer a cost effective and convenient solution to the problem of gaining access to circular ductwork for maintenance. Manufactured in a wide variety of sizes, doors are available to suit ductwork ranging in diam from 100 mm to 2000 mm. In addition, Ductmate insulated curved access doors also offer the following beneficial features:

	Two sheet metal construction formed by precision 'stamping' to provide increased strength.
	Aesthetic appearance.
	User friendly hand knobs to facilitate easy opening and closing without the need for special tools.
	Conical spring design which enables the two piece door to perform as a single unit.
	Oval shaped opening cut in the duct wall permits the back plate or 'inner plate' to slip easily through and due to the neoprene gasket, form an airtight seal.
