Here's an HVAC idiot that can tell you fusable heat links are very common and in every commercial building you walk into. They are necessary for any duct connection that penetraits a firewall. They come in a range of tempertaure breakage points. Meanwhile, this stupid HVAC guy who designs this crap (air distribution systems) for a living will crawl back under my rock where us unedumacated liv.
"NewsFlash" A HVAC guy did not design fuseable links for air distribution systems. That would be your lovely goverment that did that. More regulations put in place to make you "safe". The same type of regulations put in place because stupid homemoaners put flammable liquids (gas cans) up against a water heater! "Stupid is Stupid does" Bubba
