This Chore-Time Brock hopper valve kit will make it to where you can fill a bucket from the side of your hopper bottom bin. This will easily flow with grain or feed. A template will come with this to let you know what size hole you will need to cut in the side of your funnel. All the nuts and bolts come with it. There is a slide shut off on it that has a place where you can lock it to keep unwanted critters out as well. This is a must have if you want to fill buckets from your feed bin!
