This unique range of curved duct access doors are designed to provide inexpensive and trouble free access to fire and volume control dampers and associated ventilation and air conditioning equipment mounted within ductwork.
Correctly installed, these doors provide an airtight seal up to 2500 Pa. In this respect they exceed the requirements of HVCA DW144 specification, classes A, B and C.
The range of six sizes have been carefully selected to provide suitably sized apertures relative to the size of ducting selected.
Doors are available to suit duct diameters from 76mm to 2000mm diameter. Every door is supplied complete with a self adhesive template which eliminates the need for any measuring or marking out.
