Lock-Top Energy-Saving Damper

All throat dampers leak energy, even new ones. So each and every fireplace is a candidate for the win/win of an energy-saving damper such as the Lock-Top. The Lock-Top has a stainless steel lid attached to a cast-aluminum frame by an array of stainless spring wires. It comes with a 30' cable that is dropped down the chimney and is operated with a handle mounted in the firebox. Just a tug on the handle will open or tightly close the Lock-Top. It comes with a Chimney Fire Safety Device that locks the damper open in case of a chimney fire. The Lock-Top is our most popular damper and has a life time warranty.
