Periodic inspection and testing of fire and smoke dampers and detectors in ductwork is a standard safety procedure. Easy access to these devices as well as providing a means of access for duct cleaning. Duro Dyne Access Doors incorporate an integral frame which readily fastens to the ductwork as well as a camlock latching system for easy entry.

Insulated Access Doors, Hinged (DAD) or Cam Only (DADC)

Rugged Quality Construction Designed For Fast Secure Installation Without Using Tools!

The DAD Insulated Access Doors, Hinged and the DADC Insulated Access Doors, Cam Only  have been designed to create an airtight seal utilizing a moisture, oil and grease resistant neoprene gasketing between the door to the frame and the frame to the duct. The door panel is constructed out of 24 gauge galvanized steel and filled with a 1” 1-1/2 lb. fiberglass insulation (K factor .26+.03@75°F). The frame is 24 gauge galvanized steel with punched steel tabs along each side, which locks the frame into the ductwork. Smaller frame corner tabs make installation easy. Double camlock latches are used on doors 14” and larger. 12” and smaller have one camlock.

Self Stick Access Doors (NHSAD, NCSAD)

Access doors are used in duct systems for many reasons. Entry is often required to facilitate duct cleaning, examine equipment, or to test, repair, or troubleshoot system components. Duro Dyne NHSAD & NCSAD access doors provide an easy four step solution. Size and cut a hole in the duct wall. Peel the release paper from the foam gasketed access door frame. Press the frame into position. Insert one screw into each of the four pre-punched holes in the frame.
