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?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.
