Access doors for circular ductwork

Doby Verrolec has introduced a range of access doors for circular ductwork. Correctly installed, Easyfit access doors provide an airtight seal up to 2000 Pa and meet DW144 Classes A, B and C. Formed from galvanised mild-steel pressings, these doors are suitable for low-, medium- and high-pressure applications with spiral and straight seamed circular ductwork. There are six sizes for duct diameters from 100 to 2000 mm. Each door comes with a size-matched self-adhesive fixing template which is stuck on the duct — enabling it to be installed in just a few minutes. Once the aperture has been cut, the door is fitted with the locating bolts to ensure a positive seals. No rivets or screws are required, and large hand wheels make for easy installation and removal.
