Due to ongoing increases in material and supply costs, we will be implementing a 10% surcharge on ALL Cast Aluminum Blast Gates, effective June 4th, 2026. These adjustments are necessary to continue providing high-quality products while complying with regulations.
Full blast gates (also called cut-offs) are used to open and close branch ducts in a system allowing air to be diverted only to machines that are operating, thus conserving air volume. Half blast gates are used when adding a gate to an existing branch duct that is prone to clogging or a very abrasive material as this gate adds no internal obstructions. Sliding galvanized blade features a locking screw for full volume control including balancing. Ideal for Dust Collection, Fume Venting, and HVAC systems.
