How to Install a Spiral Duct Access Door

Fitting a curved duct access door to spiral ducting looks difficult if you’re attempting it for the first time but it doesn’t need to be. We’ve prepared this guide & a video in order to make the process as simple as possible.

Before you begin the duct access door installation, you will need:

  • A jigsaw (you can use an angle grinder & tin snips but a jigsaw can make things easy)
  • A drill
  • A length of spiral ducting
  • A duct access door

The Spiral Duct Access Door Installation

The access door will come with a sticker that can be stuck to the ducting in order to make it easy to cut out a hole for installation.

Try to have the edges of the sticker between the ridges of the spiral ducting in order to make it easier to cut a hole. 

Before starting to cut, use a drill to bore a hole so that it’s easier to insert the jigsaw blade.

Once you have cut around the hole, the access door should slot into place. Once it’s in, you can tighten the wheels on the door in order to tighten the seal around the hole to prevent leaks.

We have prepared a video of this which should make the process easier. We have a number of videos explaining how to do a range of ducting tasks on our YouTube channel. If you’d like to recommend any topics for us to create new videos for, please let us know.
