I had a new stove delivered to the house. My wife said the installers were wonderful except . . . they didn't install the anti-tip bracket. I'll do it later, of course, but it's part of the manufacturer's recommendations. Pros should know this and get them in for their customers. One of the many things I look for in an inspection. For those that haven't seen one of these before, the anti-tip bracket is a device that is installed to keep a free-standing appliance from falling over. This can happen in a variety of ways, from innocent babies climbing on the door when it's down, to the elderly grasping the edge to avoid falling to . . . well, failures of human intelligence.
(The only part about the video that surprises me is that it was a young lady - doing as much work as I do around university campuses, this is the sort of thing I expected to see from a frat house.)
There are two ways to secure the stove. It's not very complicated. The one in my picture is a floor mount that has a slot for the rear leg of the stove to slide into. The second method, not used as much any more, is to use a bracket that attached to the wall with a hook on the back of the stove.
Installers don't like to spend the extra time since they always have a 'next' job to get to. Not installing it, though, voids the manufacturer's responsibility if the stove does tip.
On a side note - a daughter of mine didn't understand why I checked for them, until her daughter climbed the stove. Now she gets it. And keeps telling my grand-daughter - who's a peach - to quit it.
