Walker duct sealing

[JJWalecka]

Removing dog houses with a one inch threaded walker duct fitting. What model number and fitting would I use to screw in to the walker duct to seal it?

Those are standard pipe size, so a 1” plumbing plug should work. (The ones with the recessed socket) You could use a bell box plug, but 1” would probably be hard to find.

Wasn't sure if there was something listed for it. Fire rating? Didn't think a bell box ko port would be adequate in regards to fire proofing the walkerduct?

To seal up a unused port on a floor duct they call that an 'abandon plug' if thats what your looking for:

The tombstones would not be fire rated, why would the bell box Ko be any different?
