I have a lawn roller. I drained it last fall before I put it away, and can't remember what I did with the plug can I buy a new one? Do I have to bring my roller to the store?

Yes, above the nut and bolts in hardware asile.

I called the store and they do not have the right type. It is plastic roller and plug threads in!

And you can probably take a picture of the roller and show customer service (eric king) they will be able to look into the exact size you need.
