For rusted, broken, or missing dampers, the Lock Top Chimney Top Damper is the ideal replacement and much more energy efficient than the old leaky metal on metal throat dampers. These seal super tight, have excellent spring action, and work well even when covered with snow. We stock and install the most common sizes or can order what you need.
The Lock-Top II gives the added protection of a stainless steel chimney cap surrounding your damper to provide extra rain, animal, and spark protection.
