Name that Jobo Part

This picture is stolen from an eBay auction, but it has the mystery ring that I got in a bulk craigslist purchase. What is the wide, black ring in the front-right? I can't figure out any way that it attaches to anything I have (1500 & 2800 series).

A sealing ring for the drums??

What sort of material is it made from.. softer than the drum material?

It goes on the bottom of the drum with the ring inside the lip of the drum. I have to look it up in the catalog as to name and exact function, but a new drum comes with the ring attached that way. I removed them immediately and have never used them.

It is hard plastic, same as the drums.

Thanks.

I tried inserting it in the tank mouth, which doesn't fit. I didn't think of the bottom. I'm trying to imagine the function, but failing. But it sounds like I will be fine sticking it in a box somewhere and not worrying.

It is used if you want to roll the drum manually (for example if you don't have a processor)

Ah, ha, levels the playing field so to speak. Makes sense.

Here is a picture of a 2800 drum with that ring attached at the bottom: http://www.apug.org/forums/forum37/6...negatives.html

Aha!! I have one of those ... and I didn't know what it was for either!
