Big Horn 11437 4-Inch Self Cleaning / No Clog Aluminum Blast Gate for Vacuum/Dust Collector

The Big Horn 11437 4-Inch Aluminum Blast Gate is engineered to control airflow in dust collection systems by directing suction only to the machine in use. This improves system efficiency and helps maintain cleaner work areas by reducing wasted airflow. Made from cast aluminum with a precision steel sliding gate, the unit features a locking knob that holds the gate securely in place. A full-length slot extends through the back of the gate body to allow chips and dust to clear from the groove, preventing debris buildup that can obstruct closing. This model is compatible with most 4-inch systems
