Suitable for most long narrow chimney flues between 3″ – 6″ (7 – 15cm) deep and 10″ – 15″ (25 – 38cm) wide. It comes with a 150mm / 6″ extension rod (total handle length is 300mm / 12″). Fireplaces with this type of throat tend to have them just above the fireplace so an extension rod isn’t always necessary. However, if yours is more than 6″ (150mm) above the top of the fireplace then you’d better get an extension pole too
Don’t forget that the Chimney Sheep® size should be slightly bigger than the chimney flue. If you are unsure of how to measure your flue and choose the correct size take a look at the How to Use page and the Sizing Chart.
