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.
