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 ducting.
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.
Every door is supplied complete with a self adhesive template which eliminates the need for any measuring or marking out.
Please use the drop down menu below to select the duct diameter on which the access door is to be installed.
