Chutes


Straight End	Flared End

Let gravity move your material from one area to another by connecting these chutes to conveyors and other machinery. Originally designed for cement trucks, the extruded aluminum construction makes chutes both strong and lightweight. Chutes can be cut to shorter lengths.

Flared End—Flared chutes have a wide opening to prevent material from jamming.
