This part starts the task of passing through a wall (usually to outside).

This is a twin wall clip-together chimney part used to build a new chimney. Twin wall clip-together chimney can be as close as 5cm to combustible materials (7cm if passing through a sealed void). No glue or sealants required.

When we say 5” or 6” we speak of internal diameter: outer diameter is 7.5” and 8.5” (192mm and 217mm).

THIS PART REQUIRES A NARROW LOCKING BAND (NOT INCLUDED).

Very helpful

I bought my stove and flue from Stovefitter’s Warehouse and couldn’t be happier with the whole experience. The ordering process was fast and simple, and delivery was spot on – everything arrived well packaged and on time.

What really stood out though was how helpful they were with all my questions during the installation. I had a few queries as I was fitting it myself, and every time I got clear, friendly advice that made the job so much easier. Order number-22095

Fantastic service and great products – I wouldn’t hesitate to recommend them and will definitely use them again
