Key benefits Precise airflow control: Allows you to open, close, or modulate airflow to balance ventilation, reduce drafts, or finetune combustion air. Durable construction: Cast iron body resists deformation and handles repeated operation for long service life. Simple compatibility: Sized for 6' ducts and flues, making it suitable for many residential and lightcommercial venting needs. Improved system performance: Helps reduce energy loss and unwanted backdrafts when properly installed and adjusted. Key attributes Brand and model: Imperial Manufacturing Group BM0051A Size: 6' (sized for 6inch ducting or flue connections) Material: Cast iron body for durability and stability Function: Damper for regulating or isolating airflow in duct, vent, or flue systems Typical performance: Designed to provide reliable operation for airflow control in appropriate 6' venting applications Typical applications / use cases Fireplace or chimney flue: Use as a damper in a 6' flue to control draft and reduce heat loss when the appliance is not in use. Wood stove or solidfuel appliance venting: Install in the flue run to adjust combustion airflow and improve burn control. Small HVAC or exhaust duct isolation: Use in 6' duct runs to isolate sections for maintenance, control exhaust flow, or balance air distribution in workshops or lightcommercial spaces. Installation and maintenance notes Intended for use with 6' ducting or flue connections; confirm pipe/duct dimensions before installation. Installation should follow local codes and manufacturer guidelines for the appliance or venting system. If in doubt, consult a qualified installer or technician.
