Some extrusions have weights in them. For
example this one has a galvanized steel weight
inside the bottom rail.
And this is what it's supposed to look like. It
is galvanized steel which means it has a
tendency to corrode.
So let's go take a look at what one looks like
when it is corroded. Now if you take a look,
you can see, look how fat that is.
We have a lot of what we call, door pregnancy
going on there. And that is very very serious.
It can actually destroy the door.
And I want to show you why that's the case by
actually going to a door that is up and moving.
So here's an example of that rail. ok.
So if it was really really fat like this? How
is it going to move past this? And that's what
happens in these types of door systems.
So having that galvanized piece of steel in
there, is not a good idea. And it takes
specialized understanding of how to remove
that, so that you don't actually destroy this
piece of metal.
We've created a special tool for that and we
were able to remove this piece without
destroying this piece of metal.
And then we put the whole thing back in shape
and were able to correctly fix the door.
