I received my replacement fire extinguisher yesterday.
called on 1/31/18, received replacement on 2/8/18
Kidde replaced an E10 (Canadian unit) with an FC10
The E10 had a red plastic trigger lock that has tabs that kept it from falling out. The FC10 has a metal trigger lock - only held in by the yellow strap for shipping (which I snipped off immediately).
With the extinguisher mounted with the pressure gauge and trigger lock against the wall the trigger lock won't come off or fall out, but it will rattle (metal trigger lock against metal trigger) like the dickens in the MH while going down the road. Leaving on the yellow strap would not make a difference. I'm now kind of liking the plastic trigger lock.
