4'' Metal Blast Gates
Heavy-duty construction is longer lasting and less likely to jam than plastic blast gates. Designed to fit inside the 4" clear flexible hose. For more simple, convenient, and stable operation, use our blast gate wall bracket (sold separately). It attaches to both the wall and gate, eliminating the sloppy hose movement that occurs when opening an unanchored blast gate.
WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood.
