The Shieldmaster increasing adaptor from single to twin wall takes you from 7 inch single wall up to 8 inch twin wall pipe in one go. It is the first twin wall flue part you will need for your twin wall flue installation. It connects either directly to your stove spigot and then upwards to your twin wall pipes or to the length of enamelled pipe coming out of the top of your stove. It is usually recommended to come striaght out of the stove with a length of enamel pipe as this pipe is both cheaper and harder wearing.

This product does not come with a locking band, as the next part you attach it to comes with a locking band. Attach the bottom of this product to your stove pipe or spigot with fire cement and the top connects directly to your twin wall pipes.

Please note - as with all twin wall parts the diameter quoted is the internal diameter - the external diameter is 2 inches larger due to the surrounding insulation.
