About Lock-Top

The Lock-Top damper system offers a smart way to control your chimney's airflow and keep your home comfortable year-round. These devices are designed for homeowners who want to prevent energy loss and moisture buildup when their fireplace or wood stove isn't in use. When selecting a Lock-Top, consider the shape and overall dimensions of your chimney's flue to ensure a proper fit. It's important to determine the cross-sectional area and the specific flue sizes your chimney utilizes, whether it's a standard rectangular shape or a round opening. Thinking about these dimensions will help you choose the right Lock-Top damper for effective sealing.
