Garland GLCK4522266 Air Shutter Open Top Kit 2-1/2" OD X 1/2" ID

The Garland GLCK4522266 Air Shutter Open Top Kit 2-1/2" OD X 1/2" ID manages the airflow to the combustion chamber by using the shutter opening to adjust the air-to-gas ratio in the combustion chamber as the gas enters the burner. The open-top design allows visual verification of the opening during burner operation to allow mechanical adjustment of the tuning instead of electronic adjustment. It is put on open-top range burner assemblies at the venturi, between the gas supply and the burner head. The kit is compatible with burners of an interface applied to open-top equipment as a service or replacement.
