An excellent retrofit to any dust collection system, these self-cleaning blast gates have a modified slider that automatically clears chips from the gate track, preventing debris from inhibiting gate closure, which is a common cause of poor suction.

The 2" and 4" sizes are compatible with our 2 1/2" and 4" flexible hose (though the 2" requires a small overwrap of tape to improve hose fit); the 5" and 6" gates are for systems made of metal ducting. Steel and cast aluminum, these are an economical means of improving your system's efficiency and minimizing maintenance.

A 2 1/2" key hose clamp is available separately.
