CB60M

For routine maintenance cleaning, the CB60M is a 6 inch cleanout spung ball made for cleaning tasks in commercial and industrial systems, and it is built to be inserted and removed without much fuss.

Made for 6-inch lines, so as long as you're working with a 6-inch cleanout opening, it'll drop right in without any fuss. The fit is meant to be snug enough to do the job but still easy to pull back out when you're done.
