In this video I want to talk to you about stud frame walls and what this
0:05
means for you as someone who will probably be anchoring more than the
0:11
usual number of things to walls, especially grab rails and handles and
0:16
maybe some low-level shelving or something like that. What you see here is
0:21
a pretty typical stud frame wall and the vertical pieces of wood are what you
0:28
call studs. Now in a finished home there'll be some kind of siding or
0:33
masonry on the outside typically and on the inside there'll be drywall. Now the
0:39
things that you need to anchor for successful seniors living need to be
0:46
anchored to something more than just drywall in the usual way. Ideally it
0:53
would be great if there was a stud existing within the wall wherever you'd
0:59
want to anchor a grab rail say and that may happen now and then but chances are
1:05
not many of your grab rail locations are going to match with the location of a
1:11
stud and even if they did line up on one end you still have the other
1:16
end of the grab rail to install and it's almost certain that that one's
1:21
not going to land on a stud. So the question is what to do about this. This
1:26
is not a problem that is restricted to people renovating for seniors living
1:31
either. Anyone with a home that's got drywall on top of a stud frame is going
1:37
to face this sort of problem from time to time. What you see here is the usual
1:42
way of dealing with that. The photo on the left is one of my toolboxes and
1:47
those green cylinders would be pushed into a hole into drywall and then a
1:54
screw could could be driven into the anchor. The screw can grip into the
2:00
anchor pretty well. The anchor grips to the drywall by friction and this is fine
2:06
for light-duty things but it will never do for a grab rail or anything that you
2:12
depend on to support you. The anchor in the middle somewhat better. These are
2:18
threaded anchors so you you drill a pilot hole so a smallish hole in the
2:24
drywall and then you drive these white coarsely threaded things into that hole
2:30
So instead of just relying on friction to hold the plastic anchor to the sides
2:35
like the first one the green ones, this actually grips the drywall with these
2:41
coarse threads and that gives you a lot more strength than just the push-in type
2:48
of anchor. But in my opinion it's not enough strength for a grab rail which
2:54
should be able to hold maybe three or four hundred pounds of force at least
3:02
And that's important for people who don't even weigh three or four hundred
3:05
pounds because when you need a grab rail, let's say you're slipping and you're
3:10
going to be putting extra weight on it. It's going to be kind of a shock weight as well. See the grab rail needs to be able to withstand that and I wouldn't, you
3:19
know, the white threaded anchors may work okay but may work okay is not good
3:26
enough in my book. I want things to be absolutely reliable. So the anchors on
3:32
the right are better yet than the white ones. They go into the drywall but when
3:40
you tighten and they come with a screw, a mounting screw, you can sort of see the
3:44
threads in the drawing there or in the photo. When you tighten the screw that's
3:51
part of the anchor it causes wings of metal to expand outwards and provide
3:59
some resistance on the inside of the drywall. So you can't see it but these
4:05
wings spread out and they kind of act like a like a snowshoe or something
4:10
like that to spread out the load on the backside of the drywall. Now this is
4:15
better and probably acceptable but there is a better option yet and that's what I
4:22
want to show you here. These are very heavy-duty anchors and they're actually
4:28
made especially for anchoring things like grab rails, handles, other things. They operate on the same principle. Those black, those three black fingers I
4:42
guess you could say with the dual holes in the end, those are the
4:46
things that splay outwards and grip the drywall from the backside. So in a sense
4:53
it's the same theory as the metal ones you just saw but these fingers are much
5:00
larger so they're going to be spreading the weight out even over a larger area
5:05
and they do spread out when you tighten the screws that come with the system. So
5:12
as I said these are especially made for anchoring the kinds of things that homes
5:18
renovated for seniors are going to need. In fact the one on the left is actually
5:23
specifically made for grab rails. The other one is similar design. It's a
5:29
little more flexible. It's just the one point anchor but something like this
5:34
works really well. Now if you are doing the work then of course you're going to
5:40
need to know about these things but even if you hire a contractor don't assume
5:45
that that they understand this. Many contractors don't. There aren't too many
5:50
contractors that understand all of the details and all of the options and all
5:56
of the hardware that's out there for senior living type renovations. So you
6:03
either need to know about it for your own work or you need to know about it to
6:08
explain it to someone else who's going to be using it. And just finally
6:16
here's the grab rail. I mean it's just a typical grab rail. In this case it's
6:20
installed on ceramic tiles on a wall and this is not unusual in a bathroom
6:26
and you might be wondering well how can I get through the ceramic tiles? Well the
6:33
the answer is the kind of drill bit you see on the right. This is a masonry drill
6:37
bit. It's meant to go through the very hard material of ceramic tiles and
6:44
they are very hard. A regular drill bit will not go through. It'll just ruin the
6:50
drill bit. There are other drill bits you can get that are similar to this in
6:54
that they're made for drilling glass so they have a kind of a triangular point
6:59
Quite a prominent triangular point that's that's brazed to the metal body
7:04
of the drill bit. That's the kind of thing you're going to need in order to
7:09
drill through the ceramic tiles and even in a situation where they're in place
7:15
you still have that whole stud wall business behind it. So you're probably
7:21
not going to hit the wood of a stud with an anchoring screw. I mean
7:28
if you could that would be great. All you'd need is the screw driven into the wood. That would be plenty strong but chances are that's not going to be an
7:34
option for you and it's not certainly not going to be an option everywhere you
7:38
need to anchor things. So remember the right kind of anchors and when you have
7:44
to go through ceramic tiles there are drill bits for that too
