Blast Gates
Stainless Steel
Gate Material
Control the flow of air and material through duct systems.
Aluminum is more lightweight than stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than galvanized steel. 316 stainless steel has excellent corrosion resistance.
ABS plastic gates work with plastic duct and duct hose. They withstand impact and abrasion.
On gates with a locking screw, use the screw to hold the slide in position. Gates with a stay-put slide do not require a locking screw.

Easy-Install Blast Gates
Often added to existing systems, these gates install without disassembling duct. Also known as half gates, these blast gates control the flow of air and material through duct systems. The locking screw holds the gate’s slide in position.
304 stainless steel is more corrosion resistant than galvanized steel.

Self-Cleaning Blast Gates
Use in dust collection systems. The slide pushes through the top of the gate to clear debris. These blast gates control the flow of air and material through duct systems. The locking screw holds the gate’s slide in position.
Aluminum is lighter in weight than stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than galvanized steel.
