A leaky throat damper is like leaving a window cracked open 365 days a year—costing you hundreds of dollars in lost heat and conditioned air. The Lock-Top™ Damper mounts at the very top of your chimney. Constructed from cast-aluminum and stainless steel, it forms a rubber-gasket airtight seal to prevent heat loss, water intrusion, and animal entry.
