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"e 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.
