Just put the arrestor in a section of the duct that is designed to be able to be removed and replaced.

I think that it's worth mentioning that I've had experience with properly vented
flammable cabinets that the flame arrestors corroded and gummed up within about
5 years of installation and significantly reduced air flow through the hood.. The
screens were welded into place, so replacing them was not an option.
