Minuteman X307281 8" Chimney Damper - Cast Iron
For larger chimney pipes, it is even more important that they be fitted with a damper that is solid enough to keep debris out and strong enough to function for many years. Minuteman's cast iron damper does just that, and it comes in multiple sizes to match differing pipe diameters. If your chimney measures eight inches across, choose this model for a perfect fit. Control the opening at the top of your chimney, allowing your stove to vent effectively but also giving yourself the option to seal the chimney during the long periods that your stove is not in use.
