Rain entry into dead chimneys is one of the main causes of structural decay to chimney stacks. Saturated by rain entry they never dry out in winter where there is no fire. The freeze/thaw cycle causes a steady degradation of the mortar and masonry at great ultimate expense.

The Brewer chimney capper is a simple value-for-money answer that prevents rain, bird and debris entry while still allowing nominal ventilation, essential in dead chimneys. Instant simple fitting to chimneys between 150mm and 250mm internal diameter is achieved using the stainless steel strap.


Colour Black
Diameter 150mm - 250mm Material Aluminium

Reviewing Chimney Capper Metal Chimney Cowl Round Strap Fix - Natural

It said it was made from stainless in the description, but it's not it's made from aluminium. Couldn't be bothered with the hassle of returning it. This is the drawback of buying online, you're relying on the description being accurate!
