Dust collection blast gates, such as Rockler StableGates, Tool Port Blast Gates, or Tool Port Blast Gates are 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.

Basic Dust ֱ System Layout

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.

Blast gates cut off the suction to tools that are not in use, focusing the dust collection suction on the tool that is being used.

Tool Port Blast Gates


The Dust Right Tool Blast Gates let you control the flow of air and dust where it matters most: at the tool. Just reach down and open the gate—it couldn't be simpler. Buy one for every tool you have for optimal efficiency. By closing gates when you're done with lesser used tools, you can maximize the vacuum in your system. These two Tool Blast Gates feature a flexible end that conforms to the slight variations of either a 4" OD tool port (left) or a 2-1/2" OD tool port (right). The rigid end of both ports accepts standard 4'' ID hose.
