Easy-Install Blast Gates
![]() |
Add a blast gate to your system without disassembling the run. To install, cut a thin slot in the duct for the slide blade, and then mount the collar to the outside. Gates open and close to control airflow to sections of duct. They’re commonly used in dust collecting systems, either to direct suction or collect dust in a specific section. Also known as half gates.
Aluminum with Galvanized Steel Slide—Our most popular blast gates. The body is aluminum to reduce stress on your duct and the slide is galvanized steel for strength. Both components resist rust in wet environments.
Aluminum with 304 Stainless Steel Slide—These blast gates have a 304 stainless steel slide that holds up to moisture and mild chemicals better than galvanized steel. The aluminum body reduces stress on your duct.
