The optional 36″ extension comes with different matting config and legs. It can be run at a lower pitch and tuned for super fines. Longer sluices are needed the heavier your feed rates. If you haven’t learned about INCREMENTAL PROCESSING…. read about it or watch our videos. It will teach you about sluice length.
Extension simply bolts on the end with two wingnuts.

To attach the extension…
Lay the mat inside the extension. It will overhang on both ends.
Now lay the upper sluice on top of the extension and matting.
Drill a 1/4″ hole through both roughly 1/2″ away from the edge.
You’re all done.
We don’t add a “hold down” system to the extension as the mat stays in place.
