8 X 17 Lock Top Damper Chimney Cap

Replace your fireplace damper with the lock top chimney damper. Keep heat and energy in...rain and animals out with the Lock Top chimney cap damper. The Lock-Top Damper seals tight with a silicone rubber gasket. A Lock-Top Damper seals tight, so virtually no air, and thus no heat or air conditioning gets lost up your chimney. The Lock-Top also eliminates downdrafts, seals out rain which can deteriorate the inside of your chimney, and prevents entry by pests like squirrels, raccoons, and nesting birds. A cable drops down your flue and attaches to a handle which mounts where you can reach it for convenient opening and closing.


Will fit 6" X 14" to 9" X 17 1/2"
