The Lock Top is the practical way to replace ineffective or inefficient throat dampers, combined with the protection of a chimney cap

Unlike a cap or wire screen, the Lock-Top totally seals chimney tops, ELIMINATING COLD DRAFTS AND HEAT LOSS

It also acts as an excellent means of pest control, preventing them from entering the chimney.

The damper mounts at the chimney top and is controlled by a simple mechanism conveniently located on the sidewall of the fireplace.
