The hopper extension is constructed from 20 gauge G90 hot dip galvanized steel that should never rust. The material is more than 35 thousandths thick, and is super strong! The pieces are laser cut, and then CNC bent by our supplier in the USA. The hopper extension increases the total capacity is up to 39lbs, perfect for all 10 gallon batch sizes, and a single hopper fill. Made of the same durable materials, and bolts directly onto all of our existing hoppers with a perfect fit. Sold as an add-on to your new or existing hopper.
Because the parts are built very accurately, the holes line up perfectly. The whole works assembles easily in minutes with the included #8 machine screws, washers, and nylon insert lock nuts. We include nylon insert nuts so they won’t vibrate loose while milling. The hopper mounts to the top of the mill using the included ¼-20 half inch long mounting bolts. If you had an erector set when you were a kid, the process should bring back fond memories. (hopefully!) The only tools necessary for assembly are a Philips screwdriver PLUS an 11/32” box end wrench, socket, or a pair of pliers.
