If you have a Sioux bulk feed bin that is round at the bottom and measures 16" then this part will fit your bin. If you have an older Sioux bulk feed bin that is square at the bottom and that bulk feed bin measures 25" then we can make this part work with your bulk feed bin but we will need to add another part to your order. In this case, order the Collar Adapter 25.0 to 16.0 option below for your feed bin.

Comes complete with all hardware

If you have an older Sioux bulk feed bin then you will need this adapter to reduce the size of the hopper on your older bulk feed bin to fit the new Poly Boot & Unloader (item number S155189) for your bulk feed bin.

Gain easy access to hopper bins. This is the easiest, most effective way to draw small amounts of material from hopper bottom bins. Push the handle up, that slides open a gate mounted on the side of the hopper. Fill a tea cup, a bucket, to a feed cart. Pull the same handle down to stow the flow or close the gate. It's easy, quick, and a one handed job.

Collar requires 30 nuts and 30 screws.
