A Top-Lock damper can save you energy because it creates a tighter seal than the usual metal-to-metal damper of most fireplaces. It consists of a stainless steel lid attached to the cast aluminum frame with steel spring wires. It closes tightly with a silicone rubber seal when the fire is not lit. The unit operates because of a 30' cable that passes through the chimney and mounts in the firebox. It also has a safety device that locks the damper open in the case of a chimney fire. The item carries a manufacturer's warranty for all fuels. Top sealing are not recommended for use with gas logs because of the risk of inadvertent carbon monoxide buildup. The dimensions of the damper are 8" W x 13" L and it fits inside flue sizes of 6" x 9" to 9-1/2" x 12-1/2". It has a cross sectional area of 49 square inches.
