Blast gates, like these Rockler StableGates and Metal Blast Gates are hose ports that feature a sliding gate that opens and closes to control the airflow in your dust collection lines. They're like the traffic cops in your system. In this Rockler demonstration you'll see several types of blast gates and how to install them in your dust collection system.

Anatomy of a Dust Collection System

Dust collection systems that run to multiple tools typically feature a main line, often called the trunk line, that runs from the dust collector and secondary lines, often called branch lines or drops, that run to each tool.

Why Install Blast Gates
